Well, I bought at Amazon DE and I have long since entered my keys which appear in my account on this page. Nonetheless I am not allowed to log in right now...

Edit: Forget it, I actually did forget to enter the retail key from the box! I thougt the lifetime subscription would take care of everything. Plus, I didn´t visit the forums the last few days... So if anybody has the same problem which actually doesn´t seem to be the case... the problem is most likely sitting right in front of the screen. ^^

Thank you Cryptic, STO still rocks!
