Problem with MP Classic opening H264 AVI file

Hi everybody,
I installed my ghost and my all codecs are gone. I used to play H264 coded files with MP Classic but right now from same file i m getting this error message:

Who has any idea what is missing or i ignored? By the way, i installed x264 codec but it didn’t work out neither. Thanx…
