Lightworks activation troubleshooting

I enter my username and password at the ‘welcome' screen Lightworks says
"Unknown username/password - please try again"

To confirm that your username and password are correct:

  • Sign out of lwks.com.
  • Write your username and password in a text document.
  • Sign in to lwks.com again, copying and pasting the details from the text document.
  • Once you've confirmed that they work, copy and paste them into the application.
  • Note that both username and password are case-sensitive and be careful to avoid unwanted spaces.

If you need to be reminded of your username:
www.lwks.com/remind-username

If you need to reset your password:
www.lwks.com/reset-password

I can sign in to www.lwks.com, but the software still says
"Unknown username/password - please try again"

Double-check the credentials using the method above. The password field should accept all characters, however there may be exceptions - try resetting the password:
www.lwks.com/reset-password

I can sign in to www.lwks.com, but want to change my password anyway

If you're able to sign in, do so and then visit www.lwks.com/account-settings.
Enter your new password into the two password fields and then 'Save'.

I have confirmed that the sign in details are correct, but Lightworks says
"Cannot connect to licensing server". It offers me 'offline activation' only.

Connection issues are caused by a break in the communication between your computer and the licensing server. This break can be caused by a variety of things, including your router, firewall, anti-virus, local network and internet service provider.

Test your connection to the activation server - see the following entry.

How to test your connection to the activation server

In your web browser visit https://els.editshare.co.uk/test

This test page will confirm whether or not your computer is allowed to communicate with the licensing server, connecting through port TCP/443.

Possible results:

  1. I see a message similar to "404 - Server not found".
    We work hard to ensure that the licensing server is always accessible. If the server cannot be found it's likely that the problem is ‘local' (specific to your computer/network/internet service).

    Check your internet connection. If the connection is working but the test page is not found, there might be a problem with your DNS service, or your computer might be connecting to the internet via a Proxy server (which in turn might have DNS problems or restrictions).

    Recommendations:

  2. I see a message similar to "You can't access this page, contact network administrator".

    This indicates that a local firewall restriction is stopping access to els.editshare.co.uk on TCP port 443

    Your firewall might be managed by your operating system or by your AntiVirus software. Please refer to the appropriate documentation.

    OS specific instructions
  3. The test page https://els.editshare.co.uk/test won't load or is timing out:

    Set your web browser to visit www.lwks.com

    1. If www.lwks.com is also timing out your IP address may have been blocked by our firewall, you can confirm this by checking from another IP (either another computer or via a proxy).

      To resolve the problem contact us at This e-mail address is being protected from spambots. You need JavaScript enabled to view it quoting your IP address which can be checked at: whatsmyip.org

    2. If www.lwks.com works but https://www.lwks.com does not - this suggests that local firewall rules for port TCP/443 are incorrect (see setting your firewall rules above), OR the activation server els.editshare.co.uk is blocked by your ISP or Proxy Server - contact your network administrator.

  4. The test page confirms that I can connect, but the software still won't activate::

    Please zip up the Lightworks log files from:

    • Windows: C:\Users\Public\Documents\Lightworks\Logs
    • Linux and Mac OS X: ~/Lightworks/Logs

    Send the zipped files to This e-mail address is being protected from spambots. You need JavaScript enabled to view it with your lwks.com username

Offline activation procedure

Watch the Video Tutorial

Instructions can also be found on page 10 of the Installation and activation guide.

  1. Start Lightworks, enter your Username and Password and click Continue. NOTE: Make sure these credentials are exactly the same as on lwks.com

    If the internet is not detected a panel will display asking you to start the offline procedure, click OK
    The shark.c2e file is then generated here:

    • Windows: C:\Users\Public\Documents\Lightworks
    • Linux and Mac OS X: ~/Lightworks

    Copy shark.c2e to a removable drive and take it to a system with an internet connection

  2. Upload the shark.c2e file to lwks.com:

    • Go to this page: www.lwks.com/activations (you will need to be signed in to access this location)
    • Under "Your Machines" you will see the "Add a machine" option, click the "Browse" button Browse to and select the shark.c2e file
    • Click the "Upload C2E file" button
    • Your new system will then appear at the top of the list with an orange border.
    • A Free license is applied to the system automatically.
    • If you have a Pro and/or AVID DNxHD license, drag and drop to the system.
    • Click the "Details" drop-down arrow to confirm your selection, then click "Download". A shark.e2c file will be generated.
    • Take this file to the system you generated the shark.c2e from and copy it into:
      • Windows: C:\Users\Public\Documents\Lightworks
      • Linux and Mac OS X: ~/Lightworks
  3. Start Lightworks, enter your Username and Password and click Continue

    NOTE: Make sure during all three steps the same account and password are used or the activation will not work.

I get an error message: "license expired"

If you are a Lightworks Free license user, make sure you are running the latest version (12.x), available from the Downloads pages. If you have the latest version, but the issue still occurs, please Report a problem.

If you are a Lightworks Pro license owner, visit the Activations page and confirm that the license is date-valid. If the license is within date and should therefore activate, please Report a problem. If the license has expired, you can purchase a new one in the Shop.

I get an error message: "Invalid Response from ELS Server"

This may suggest that there's a technical issue on our side.
Please email the following file to This e-mail address is being protected from spambots. You need JavaScript enabled to view it and we will resolve:
