Hi vadymmyk-

Sorry to hear you're having this issue. A few questions:

-What OS are you using?

-What is the plug-in/is it the latest version?

-Do you have the newest iLok Manager installed?

As a preliminary suggestion, I would use iLok Manager to remove the license from your device, reinstall the plug-in, and then move the license back to your iLok/computer.

Best,

Tom
