no serial number

[bubba48145]

ok, so I bought a pack at walmart that has Armored Princess and Crossworlds on it. it installed fine and I started playing just to make sure everything was fine. I saved and exited out and then proceeded to look for patches to bring it up to date. I found my way to the official site and saw the hotfix on the main page and installed it. now when I try to start the game it asks for a serial number which I don't have. there was no physical manual in the case and the .pdf manual has nothing. can I simply not patch my game and will uninstalling and re-installing let me play again? if not, is there any way I can get a serial number and get through this frustration?
