Won't let me check out?

By WanderingShiren, in Twilight Imperium

Hi, I just heard about the release of the fourth edition of TI. Obviously I would like to preorder the thing, such that I can have it near release, but every time I go to check out, it says my card year isn't valid? Is anyone else having this problem? Is there any way to fix It? Thanks for any help!

Solved! I'm just an idiot as always. :P
