BS Player error messages - Windows Media Player no problem

[Ivo]

I installed the new BS Player on my laptop using Vista Business (I have Vista codec pack installed in my computer). It does not play any movie, always an error report:

BSplayer v2.12.941, Unhandled exception at EIP: 04BC23F9
If you click 'Close' application will be terminated.

Windows Media Player plays any of these movies without a problem. What is going on ? BS Player seems unuseable now ...
