Thanks for the quick reply.
I read what you said then tried a couple of things.
1. I deleted Crismons Skies from the 1.6 box. I have Crimson Skies on a v1.0 box that runs fine so I re-transferred it from the 1.0 xbox to the 1.6 xbox via Avaluanch.
2. Deleted all the files in the e:/cache folder, x, y, and z drives.
3. Reset the menu cache in MXM.
4. Rebooted the 1.6 box
Tried to launch Crimsons Skies, box froze at the end of the MXM load screen and Crimson never started at all. I had to do a hard reset to reboot.
Next, I launched at LEAST 10 other games to see if they worked, they all launched fine including Conflict Desert Storm 2. Unfortunately, I do not have Enter the Matrix or I would have tested that one too.
Am I missing anything else?
