hi there, i was running a trial version for some days now, everything was fine but i had some problems with my pc in which i had to uninstall several programs, including dopus, after everything solved i installed dopus again but to my surprise it now says my certificated expired, which is not true.. i even tried using a new trial certificate and it doesn't let me (which seems normal since i was using one already)
any ideas?
When was the original evaluation certificate issued?
The trial period is 60 days and your post history shows you've been using Opus longer than that so it seems normal that it's expired now.

Hehe, no Raymond Chandler skillz really, I just noticed the join date on the left and clicked Profile -> Find All Posts to confirm it. 
it's true, i've been using it longer than the 60 trials, simply because i've formated my pc, is that illegal?
I don't know exactly what the eval rules say. Either way, contact GPSoftware if you want an extended evaluation. (Or buy the program.)
