Avisynth: is not a valid integer value ?
 

that's the message I get when loading the MA script (without alteration) into ToK. Problem is, which " is it talking about - there are a few there?!
It seems other people have had this problem but I couldn't find any explanations on the other threads so what do I do to fix this?

Strange known problem with Tok. Reinstall it completly and the message should be gone.

Nothing wrong in the MA script.

Yeah, tried that, didn't help. However turns out the tok.ini file had gotten messed up, once I replaced it everything was fine.
