"Can't open file" with .avi 's

[coheed]

For some reason, a few of the movies I was able to watch before I reformatted aren't working now with BSPlayer since I get this error everytime I open them. I'm pretty sure the only codecs I had installed were xvid, divx and wmp9. I've got those same ones, but for some reason it won't play these avi files. If someone could help me find a solution I'd be really grateful.

edit:

I've got Windows ME, the above drivers installed, using BSPlayer version 1.36 and Build 825, Sept 2 2005
