On older builds I've resolved this by deleting everything except the CatIntel__Setting.xmp and CatalystPreset.txt. In worst cases, I have had to delete the CatIntel__Settings.xml which sucks but as long as everything from the mixes are stored in the CatalystPreset.txt (basically stored as presets) then I only have to reset the basic settings of Catalyst.

This could be caused by and issue with a video capture device not present on the machine you're reopening with.
