How to keep using the free version?

How can I continue to use the free version? I got a message that I am no longer able to keep using it unless I have a license (??).

Should I uninstall it and install again ?

Please kindly advise, thank you.

Best regards,

Are you at the just at end of the 30-days Pro trial? All you need to do is just register yourself for a free license. You’ll still be able to use it, just with some limited features.

Or did you get an email about violating the terms of use by using a free license for commercial purposes?
