504 Gateway Time-Out Error When Trying to Purchase

I’m currently trying to purchase the Wayfarer package. I’ve signed up for a GA.ME account, and verified my email addy. I click the Buy Now button, enter my username and password, and after a few minutes, it gives me this error:
504 Gateway Time-out.

I’d really like to be able to get on the game tonight. Please help.

We are sorry that you have encountered this error. I have asked an engineer to look into this. He may ask you some questions.

Looks like your purchase has been successful (you have the “Wayfarer” title now) - are you still having any problems?
