Microsoft to transfer file via Xbox live to make my game backup not work?

[Big Country]

Is there a way for Microsoft to transfer some type of file via Xbox live to make my game backup not work?

I bought Ninja Gaiden and it plays fine but when I made a backup I removed the Jap movie files and not the automatic update file before I burned the copy and it tried to update and I guess I got banned from Xbox live because all it says now is that Xbox live is not available now and to try again later. It’s been saying that for a month now. Anyway my backup of Ninja Gaiden worked fine for that first day and Never worked again. I can get through the introduction and after it asks if I want to play the regular or hard version it says the disk is dirty or corrupt every time at that exact place. I burned another copy and removed the automatic update file but it still does not work. I have cleaned the laser, tried 4 different types of media including Taiyo Yuden, deleted my ISO file and FTP’d the game over to my computer several times and burned it again in case the files where corrupt, removed my Xenium Ice chip and replaced it several times. I am using the M8 bios.

My other backups seem to work fine most of the time. I backed up a couple the other day and tried them right after and they worked but neither of them would work the next day and they both work fine today.

I'm pretty sure that it is not the Chip. Not the media. Not the ISO file. Not a dirty laser.

I don’t know anyone else with a modded Xbox to see if the backups I made will work in their Xbox so I don’t know exactly what is the problem.

Any ideas???
