You guys are life savers. I was getting ready to go buy a new xbox and start the whole process all over again.
I can't believe they would put such a setting in XBMP to cause something like this to happen, but live and learn I guess.
One more note I would like to leave you all with for your amusement.
In my excitement to apply this fix, I labeled the Enigmah disk, and forgot to burn it. Took a few reboots and some messing around before I realized there was nothing on the disk to fix the xbox. After I remembered to burn it, everything came back up like a charm.
Thanks again to all you very helpful peeps.
