Well I've been trying for over an hour(across two days) to checkout and can't get it to work. I'm getting this error every single time:

"Your Payment Provider has not authorised your purchase. This may be because some banks (incorrectly) believe that Green Man Gaming is a gambling website. Please contact your bank to discuss your order. We are working with these banks to resolve this issue."

First of all, the UK spelling of authorized gives my post red squiggles, and it's annoying. :P More importantly I've tried everything I can think of, including using Paypal funds directly(so it's not any bank issue), and it's still failing on the final purchase screen.

I've purchased through them no less than 2 times before, with these same accounts and settings... Once that was only about 2 months back... so what's wrong?
