Greetings, I wasn't sure if I should start a new topic or post on this one since I am having a problem very similar to The Fox.
I do everything that The Fox described, however when I press the [Proceed with Order] it brings me back to step 2 with the Select Payment step. I have tried this several times on three different browsers, and already consulted the forums for a solution. The one topic I did find mentioned some things to check with my account and I made sure things like the billing address are identical.
I know I have purchased from Paizo before as well, so this has just left me baffled. Thanks for any help.
