I bought Halo 1, I installed and it worked just fine, I even played a little. But when I went to play online it said I needed to download an update. after I downloaded the update every time I tried to even start up the game it my computer would say Gathering exceptions Data! And then the game turn off and say there was an error. Do I have to change security settings (if so, what to do?). Or will I just never be able to play online. I payed for this game at GameStop, so it's legal and everything, and it's not used. What do I do?
