Ok...I'm a Computer User, Non-Technical, so the answer is probably right in front of my nose...
I downloaded the Stardock Central software. I pushed the update program button, and it tells me that my serial number is incorrect.
On the jewel case is one Serial Number, on a piece of paper contained in the box is a second number. I've tried both so many times its inappropraite.
Alternately, when I push the register button, a message comes up saying "Your accout information has expired, would you like to renew?" If I push no, I can't register, if I push yes, it takes me to Stardock website and looks like it wants me to buy things!
Please tell me what I'm doing wrong!
