I have the same error message. I thought I was the only one that have this problem. I purchased a full version with a valid license sent from Karen but after 15 to 30 days later, I kept getting this error. When I looked at the modify date of the .lic file, it has changed to the trial version date. It's hard to believe that this file got changed by itself. So far, I have not found a fix for this. Cute Editor is not helpful in resolving issue besides trying another version of their .lic file.
