I can't even play my copy of Halo 2. I posted this in the xbox.com forums (Halo 2 and Support). I wanted to play a little Halo 2 the other day, and it won't play at all. I get an error message saying the game won't load and to go to the xbox.com support page. A few months ago, I purchased a 120 GB HDD and did the file transfer, so thought maybe that had something to do with it. I put on my old 20 GB HDD, recovered my gamertag, and sure enough, Halo 2 works. So I put on my new 120 HDD, had to recover my gamertag (WTF? that's retarded), and I still got the same error message as before. I deleted all Halo 2 info from the HDD except my saved game progress, and cleared the cache, and still nothing on this HDD. Does anyone have any ideas what could be wrong or how to fix it so I don't have to swap HDDs and recover my gamertag everytime (which takes an annoying amount of time)? Thanks to anyone who provides any suggestions. [Edited on 02.08.2010 6:26 PM PST]
