Halo Reach backed up but boots black screen

[stdape]

Have backed up halo reach, but will not play just a black screen when it boots.
Have lt3.0 and as far as i can see all latest firmwares

had same with dirt3

any ideas??

Run your backups through AGX360 1.06

yes forgot too add have run through abgx 1.06 seems to verify all ok, but still have problem. I have backed up other games and all play fine just this one is being a pain !!

I am sure something simple, but as all others are ok, getting cheesed off . Put a topology patch in too.

Any other ideas gratefully received

Are you sure its LT3.0? Earlier firmwares would boot to a blackscreen to prevent an AP2.5 failure
