From what I read here using the search option, this happened to a lot of users the last past years and now to me, too. Isn't anyone doing something about this issue, when it's going on for such a long time like that?
Installed Version 12 like 20 minutes ago, got a 60 days trial license file through email from GP Software and after I installed it, it says "your evaluation period has expired Code 2001A" I got that email 5 minutes ago.
The internet is plastered with people asking about the 2001A error code......not just this forum
