GordianKnot/VirtualDubMod problem

OK, so I’m trying to encode a TV episode using XviD 1.1.0 in GordianKnot. I’ve ripped/encoded countless episodes the exact same way I did these, except this time, it refuses to encode. It will do the audio, but then it says it’s complete, and there’s no video. The log says this:

*************************************
EXCEPTION: List index out of bounds (3)
EXCEPTION: Encoder Thread Terminated.
*************************************

Please, anyone help. I changed nothing from the last encode job I did, and this one. I’ve even tried different things: switching codecs, different .avs to encode, etc. Nothing seems to work.

Um... Now I feel really stupid, but hey, maybe it will help someone in the future. I tried one last thing, and it doesn’t seem to be plausible, but it worked. I simply reinstalled GordianKnot, and it worked like a dream. Hope that info helps.
