I got the game several months ago, but I just recently aquired internet service,  Now, every time i enter the registration code, I get a message that says the reg code is invalid.

I baught the game new in the plastic from game spot, and no one else but me has seen or touched it sence.

I Have tried several variations of the code.  all caps, all lower case, with dashes and without. still no dice.

BTW, I My other games have been telling me the codes I have for them are invalid as well. ( Silent hunter WOTP, Company of heroes,  and now this game to)

Could it be some sort of Internet settings / security issue?
