OK team, Error Recovery Time:
You tried opening up a photoshop file but received an error upon reload:
Could not complete your request due to a program error.
Adobe is so swamped with this question, they have included a whole PAGE for it: It can be found here: http://kb2.adobe.com/cps/331/331627.html
You may also do a spotlight search to try and delete: com.adobe.mediabrowser.plist from the preferences folder.
(Incidentally, none of these worked for me without a restart.)
What I tend to find, is that the memory capability of my machine gets too low (too many files in the CPU) and that photoshop simply is hogging too much memory. If you have less than 2GB of free space on the machine (for backup of your ram in case of a power loss) you will most likely not be able to open new files. This stops old files from opening properly AND new files from being created. What a bummer.
