The buy credits option on the market place seems to stop working..... at least for me. Well, I've tried a few time and it just gave me that error... Gave it an hour or so.... still not working.
How are you trying to buy the credits? It's working fine for me at the moment. Is this in client, on the website, through steam?
KTCAOP though poxnora site... This never happened to me before, I tried logging on and off.. didn't help. try buying the credit via the client also doesn't work
