Missing License after restart

I have a license. It is gone from the program every time I restart my pc. I can re enter it and use emClient normally, untill I restart. Then it is gone again and I have to enter it again
version 8.0.3385

Hello ursus.kirk,

Just make sure that you’re not using one license on multiple devices.
Each eM Client installation needs its own license.


I’ve forgotten to mention that I have been using emClient for over a year and never had any problems with it. It just started last two weeks. And since writing I also had a few times without any problems. It doesn’t appear to be related to anything.
