Unable to play an .avi file...

Downloading an episodic TV Series I now have a playback issue with one
of the last chapters installed; it's an .avi file and it just wont play (Screen opens and stays blank black, no image or sound). Maybe the file is bad or corrupted, but before deleting (and having to throw away all the downloading time spent) I would like to know if there is a fix. I've checked each and every one of the previous chapters installed and the only difference I can see with the file in question is a splitter filter. Whereas all previous files play correctly and in "Options" - "Filters" all show the AVI Splitter (quartz.dll - located in C\:Windows\System32) as one of the filters, the file with the issue shows a Nero MP4 Splitter Filter
located in Program Files-Common Files-Ahead-DSFilter. Could this be the
problem?
Appreciate your advice.
