Xbox softmod

Anyone reading this know anything about the software mod for the Xbox?   I got mine modded and a 300gb HD installed while I was at Anime Expo, and it all seemed to be working just fine at the time.  But now that I’ve got it home, Xbox media center doesn’t seem to want to load anymore (it hangs at the “now loading” screen) , and certain games run from the HD don’t display any graphics.    In addition, when I try to FTP files to it, i’m able to connect to the FTP but I can’t put any files on the F drive  (which is where the majority of the storage space is).  I WAS able to succesfully FTP some files to it while I was in the hotel, so I know it worked at the time.  Anyone have an idea what the problem is?


Edit: Turned off TSR from the settings menu and it worked just fine. Apparently I did something when I was investigating the various trainers that came with it.
