i`m using version bsplayer pro 2.57 1051 , it has a problem with file association ,if i put it to keep all video files when i start it it's not working,if i put winamp to restore file association on start it's working,i think the file association must be improved,as if winamp steal association on start bsplayer can't restore them,you will see them unselected if you start bsplayer and it will not restore the,i think this is a very important and stupid bug.
