Can't activate GameStop PowerUp Rewards card

I just bought a PowerUp Rewards Pro card today at my local gamestop. When I go home to try activate the card through via PowerUp Rewards - Home Page it says.

“Sorry, we couldn’t activate your PowerUp Rewards card. Make sure you entered your card number and email address correctly. If you still have problems, you can use the phone number you gave when you enrolled in-store.”

But all the information I enter is correct. Any help would be appreciated. Also I get the same message when I put my phone number in that I enrolled with at my gamestop. Still does not work.
