Error loading avisynth!

[boagz]

So I've been having problems trying to upload a vid into avspmod. The error I get is "Error loading avisynth! Make sure you have avisynth installed and that there are no unstable plugins or avsi files in the avisynth plugins directory". There is also a windows error that pops up and then avspmod crashes. This only seems to happen with a video file that I got from screen capturing on a mac in mp4 format and emailing it to myself to get it on my windows computer. Is it because emailing it does something to the .mp4 encode? or does it have something to do with the fact that the file came from a mac? I have no idea what is happening. Again all other .mp4 videos work fine it is only the one. Any help is appreciated.

I think it has to do with the .mp4 file, it is always recommended that you encode your clips into a lossless format such as huffy or lagarith.
