Looking at the debug file it looks like the game can't read the xmls
Debug Message: unable to read data from file
Debug Message: Error occurred while attempting to read xml C:\XboxGames\Galactic Civilizations III- Intrigue\Content\\DLC\EXP3_Intrigue\Core\IntrigueErrorCodeDefs.xml

This repeats for all of the xmls in that folder. I've checked the file permissions on the folder and everything looks ok. System, Admins have full control etc. (I'm launching the game as an admin)
I can't manually open any of the xml's either. It's like they're corrupted even though I've uninstalled and reinstalled the dlc.
