I was attempting to buy something about twenty minutes before the server came down for the update but it kept asking me to enter my zipcode? Then wouldn't let me type anything in the box it provided? Why would I need to enter a zipcode anyway? :/
I'd suggest submitting a support ticket to our accounts/billing team so we can figure out why you're receiving this message.
Thanks for the response, it fixed itself after that last patch though, sorry should have posted that! Thanks again!
That happened to me as well a little while back. I am using a UI that doesn't really support the marketplace though. At some point it just corrected itself.
