'An invalid currency was selected'?!?

After I enter my information, the next windows always says this.
What do I do?

Try it in a different browser. What payment method are you using? First time i'm hearing of this error.

WAIT! I figured out what I was doing wrong~
Kept going to the bottom of the Payment page and hitting 'Order' instead of the 'Order' button just below the cheat I wanted.
So it actually directed me to another page where it thought I hadn't selected an option :3
