Windows Vista - media center receiver service stopped working

A warning to anyone who cares... do not install this codec on Vista - Voxware RT29 MetaSound (75) codec

It will destroy windows media center and it will constantly crash with the error message "media center receiver service stopped working"

The only way to stop this is to manually delete all its files or run system restore. I tried this link - http://support.microsoft.com/kb/936229, but the patch they offered didn't help either.
