BitChe not starting anymore in Windows8 after some system crashes

[Mpegforever]

Hi.
Running Italian language 64bit Win8 and all was fine until some time ago. Then for other reasons I had a few system crashes and BSOD.
Now all is back BUT BitChe won't start at all. Also uninstalled and reinstalled, no way. 
Any place or something I can look ?
Thanks, ciao
