Starts on its own/ options folder won't open (possible fix)
 

File found in my sharing folder marked ' (just an apostrophe). After deleting folder everything seemed to work fine. Check folders in LW library to see what does not belong there and then delete them form your hard drive.:)

I'm having same exact problem
 

were you able to find the fix?

I think that deleting the strange folder was the fix for sirios;)
