bs player with windows 8.1 - no video

Hi there , suddenly out of the blue I can no longer open video files in bsplayer , when I open a video file I only hear the audio and there's no video. in addition when right clicking on bs player the video option is grayed out. if I open the same video file in VLC I can see the video without any problem. any solutions for this? Thanks very much

anyone? 

tried to uninstall bs player and then installed again. same results
