PlanetBonusSpacePony.entity has become corrupted and unreadable, as far as I know all I did was shut the game down.  But anyway, I can't delete it.  I've tried deleting though cmd as well, it still errors out and tells me to run ChkDsk.  When I do it freezes on stage 2 where it checks indexes.

I don't want to reformat so, is their any data recovery software out there that might be able to recover this file, so I can delete it and get the game reinstalled?
