[CLIENT] Unable to redeem Pre-paid RP card on beta client

Note: I am using the beta client currently

I have recently bought some RP from Gamestop and wanted to redeem it. However when I went to redeem it, the text box where you are supposed to type the code into would not accept any keyboard inputs. Nothing I typed would register. I also had a friend try it on his client and the same issue occurred. Hopefully this is resolved quickly.
