Ok, i re-installed Win 7 from scratch and - with my regular OD Plus 2.0 license (purchased 2 years ago) - I tried to reinstall it again. I found the original after-purchase email message from stardock and followed the instructions. Gamestop installed (instead of the well-known Impulse). The matter is: now ,in the mygames tab, there isn't any object dock entry, or rather there isn't in the whole gamestop database!
How can it be that I can't install a program I regularly purchased?
