hello well i have a problem with my halo 2 game for PC and i have called Microsoft to help me out and they said they didn't work for games, so the most resolvable thing at the time was Xboxlive costumer service since they have rights to the games (Microsoft base) i guess and well they help looking for numbers for your company (bungie) since you are the original developers. and well my problem is that they key i use only gave me asses to only the game menu, once i sing in it ask for the key again and I enter it and tells me is invalid and i use the very same key . and well that's wen i called Microsoft they said cant help i went too xbox live gave me the best service ever and they told me to forum you guys for help. pleases tell me you guys can help me out or try 343 because i really want to play halo 2 on my pc and also i don't know if the servers for PC are still up?
