Not trying to bite your head off, just trying to get something more than vauge "I booted it" answers. They don't help track the problem down.
Ok everyone, here is something to note, if you use the MSDASH item on your menu, IGR back to MXM BEFORE you powerdown/reboot the XBox. If you don't, you will need to boot off the gamesave to restore the hacked DB.
This is NOT a bug, it is by design as it is the only way to make audio tracks work.
When you run the MSDash from the menu, the gamestub is loaded FIRST. This deletes the "hacked" db and copies in the "Music" DB. When you return to MXM the "hacked" db is put back. If you don't return to MXM the "hacked" db is never put back, so the button combo will not work until you boot the gamesave. Just booting the gamesave should automatically fix this, not need to run anything once you are there.
Morden.
