You probably unintentionally changed some setting.
To return to default situation: close BS.Player.
Then rename file "BSplayer.<yourname>.xml" into anything different
(e.g. put an "x" in front of it: xBSplayer.(etc)).
(For version 1.x this file is in BS.Player's installation folder; usually C:\Program Files\Webteh\BSplayer\ )
Restart BS.Player.
Result?
