Need New Registration for Game Purchased Pre-Stardock?

I purchased O-R-B on CD-ROM about two years ago, and every time I start Stardock Central, I get a message that Stardock sees the program but the registration is incorrect.  When I try to give Stardock the ID number from the CD, it gives me an error message that the number is incorrect.  Is there a way to get Stardock to recognize my O-R-B?
