Lyx quits on startup

[Clover]

Yup, a few bounces on the dock and it's gone. Did try installing it 
again but no luck. This was in my Console log:

LyX: reconfiguring user directory
python: execv: 
/Library/Frameworks/Python.framework/Versions/2.5/Resources/Python.app/Contents/MacOS/Python: 
No such file or directory
LyX: Done!
TextClassList::Read: unable to find textclass file  `'. Exiting.

Any ideas?
Thanks!!
