XBMC Fails to OPEN

I have been running XBMC Frodo 12.1 for a couple weeks now with little issues until yesterday. First I noticed after a restart that all my movies and TV shows kept on a NAS were gone in XBMC. Strange but I figured the NAS might have lost connection for some reason so I was not to concerned. Then I tried to open a link in apple podcast and it froze. I did a force quit but when I tried to relaunch it would not open. The icon would bounce in the bottom of the screen but then nothing. After two reboots of the computer and same thing I decided to remove and reinstall xbmc. I did this twice and still it will not launch. I then opened parrallels and installed the windows version (on the same machine) and XBMC works fine in windows. This is a work around but not how I would like the set up. I need this to be easy for the family to use.

Any ideas why it fails to launch? After removing and reinstalling I do not think I have a log file.
