Problem with XviD

[Acer]

I’m a happy user of an older version of BSPlayer (Version 0.86, Build 494, 25 Jan, 2002) for many years.
However, when I click on some files in XviD format, an error message appears:

Program Error
bplay.exe has generated errors and will be closed by Windows
you will need to restart the program
an error log is being created

I’ve only installed the necessary codecs (namely, DivX, XviD, and AC3) on my computer, which runs Windows 2000. According to GSpot, all the codecs are there to play these files (XviD MPEG-4 Video Decoder + MPEG Layer-3 Audio Decoder; DirectShow claims to be able to play these files). And I’m sure that the files are not currupt.

Any help would be greatly appreciated.
