This was a nightmare...Anyways I had some issues earlyer with GJ not working right, after the V.550 update. I tryed a few times uninstalling and reinstalling running Ccleaner in between. I desided i needed a clean OS install anyways.....after the fresh install i loaded up GJ but during install "it seemed to generate a NEW profile key automaticly??" and did not prompt me to use the original? I loaded up a game that had worked earlier With a no go again? I got an error "sorry i didnt write it down".......so after crying out came the OS disc again "XP w\SP2"..on the second install then loading GJ again it finally prompted me to manually place my "profile key" "original" now all is good:clap: 
not sure if it was a bug or not "im no programmer" I just thought id bring it to your attention for what its worth.
