Hello, I'm dealing with the same problem with "fowler". GSX Base and GSX Level 2, turned into Trial mode. And then I tried to activate them again, via Addon Manager menu, with my activation codes, and the following message appeared. I have already sent an email on "support@virtualisoftware.com", because I thought that it was an activation/reactivation issue, in 18 November, but I don't have a reply yet, so I decided to post it on the forum.
I hope you can find out what is causing this problem and I would really appreciate it if you could find a solution.
Thank you for your time. I’m looking forward to your reply!!!
Andrew.
