Sorry, I didn't mean to insult anybody. What I meant yesterday, was just, that, for registration problem, the program should present with another error message, saying that there's a registration problem or if you want it to be more neutral, that there's a problem preventing the program to start and one should contact customer support.
Anyway, back to my problem. I would have sent the screen shot yesterday with my last post, but I wasn't at work and thus couldn't get to the computer where the program is installed and the problem occurs. I've attached the screen shot to this post though now.
I will try the debug version, too, and send you the log within a day.
