Hallo!
Do never open more than one support ticket. And always use the English support, because the response may come a little faster.
If you have your paid license, you can download it and put it on your SecureLine VPN. Just change the expired license to the valid license. This option is available as soon as you open SecureLine.
But... as i can see, you're not being able to remove/change the license.
To help you, please, tell us which SecureLine version you use. If it's the builtin or standalone version.
