Have you tried changin rendering modes without running Bsplayer with a file?

Run start->programs->Webteh->Bsplayer->Preferences->Video->Video Rendering and try internal renderer and overlay mixer. I had some problem with MainConcept MPEG2-decoder resulting with similiar exception on file opening, switched to internal renderer kicked the error away.
