My Bodyshop behaves the same way since BV. It crashes pretty much any time I try to run it. Deleting groups.cache, accessories.cache and cigen will allow it to run the next time I try to open it, although sometimes I have to reboot before it'll work.
I deleted both groups.cache and accessories.cache- I had no cigen, for some reason, though I know I used to. That's kind of troubling. Still no go- crashing every time I try to open it, and each time it crashes, it generates a .mdmp and a .txt file, but no cigen or groups or accessories. *Sigh*
