SMB stopped to work 24 hours after installing ATV flash (black)

Hello, as topic says, i got tired of the buffering issues in xbmc so i decided to try out firecore media player, i was happily surprised when i saw that it had none of the problems i experienced with xbmc. 

But just a day after i started to get problems with FMP, at first it was just strange errors like: playback error after playing watching for 15 sec, but now all the sudden i cant even find my smb shares in fmp or xbmc, why?! Anyone familiar with this problem and have a soulution?
