Ok, thanks, but...
What to click in the first place on the mentioned dialog
? I mean, I don't want to "lose" my activation key by resetting it and then possibly being told the key has already been used (in my first activiation) and cannot be used again.
Sorry for bothering, the thing is just that I don't know about how that activation stuff works in detail (e.g. if an activation key can be used infinitely (which would make several installations (and therefore software piracy) possible)... I need to look that up, I admit. Maybe you can provide me with some link or I'll try to find that information somewhere here on your site.
