Wierd error playing certain vid files

[Maze]

Files that always worked now I get this message in WMP: Classfactory cannot supply requested class

And when I try in BSPlayer I get this: Unknown file format(DIV3)
(someone told me DIV3 is divx 3 but I already have it and I even reinstalled to make sure)

When I try in the playa it just crashes

anyone have any idea what might be causing this? Cant think of anything that I could have installed to have caused this.

"Cant think of anything that I could have installed to have caused this."

Perhaps the NIMO codec "pack"?

If so, uninstall it - and install ONLY the codecs/filters that you KNOW you need...

But thats whats wierd Ive always used the nimo codec pack and just one day some files stopped working though...
Just tried it in vdub..it had to reconstruct missing index block what ever that means and it worked(but still only in vdub). Could it just be that the files got corrupted somehow?

"Could it just be that the files got corrupted somehow?"

Yes - and yours is the second such post this week. It's possible that those of you who resort to downloading the work of others are exposed to downloading viruses, etc. as well.

I'd strongly suggest that you immediately backup your files to CD-R - just in case...

Virus? Hmm could a virus effect somthing on a cd-r? Because one of the files thats acting up I burned on a cd months ago.

"Hmm could a virus effect somthing on a cd-r?"

Nope (but it could affect a CD-R/W)...

Cant be a virus then..this is wierd

i dont think that viruses can be in playback files, just executable files or stuff like that. so maybe you have a virus that affects certain avi files such as yours. if you have an antivirus program, run it and see, it wont hurt.
