Your account does appear to have already been upgraded to a normal account, Wongs. While you may not be able to use chat or group functionality immediately, you should be able to level past 20 at this point in time. All online upgrades can take up to 72 hours to fully complete after they have been requested and paid for.
I do apologize for the inconvenience in the mean time, but you should at least be able to continue leveling at this point. >^.^<
