When Stardock Central starts up it asks for my serial number "on the jewel case." I only have one key on a sticker on the jewel case entitled "GC2 GOLD REG CODES."
I put it in and Stardock says "The Serial Number you have entered is invalid. Please ensure the information you have entered matches exactly from your order email.
Use the Lookup Serial Number button to resend your account information to the email address you ordered under."
Thing is, I walked into Best Buy and bought it. I didn't buy it online or anything. I registered my Stardock account and all with an email address, but I never got anything regarding a key in there.
EDIT : I've entered this thing about 15 times now, suddenly it decides to work. Go figure.
I really hate users who mis-type their password or user name and then email me about how the system sucks. Guess I'm one of them now.
