Maybe it's just overly strict? This was a huge problem for PSN initially. If you didn't input your address 100%, letter-for-letter the way it was stored at the bank, you couldn't buy anything. For anyone living in an apartment like myself, that was a nightmare. I don't know if it was #### Apt. #87, or APT 87, or APT. 87, or Apt #87 or any of the bajillion combos it could have been. I didn't hear about that being an issue with GOG, though. Hope you get it worked out, it's one of the few new services to come around that I really think is fantastic and worth supporting.
