I'm trying to buy something through Gamersgate, since I can't find it anywhere else, but unfortunately it doesn't seem to like my last name. I filled the field, but it keeps refreshing and saying 'Please enter your last name' every time I press 'Confirm order'. If anyone else uses the site, what's going on and how do I deal with it?

Note: I do press 'I accept the ToU and refund policy'. I also (intend to) use Paypal to pay for the game. That shouldn't have anything to do with 'please enter your last name', but if it does, I'd like to know.
