UPDATE:
Ok, I downloaded the V4.1 files again and reinstalled all the necessary files, then started from scratch. Guess what? It worked!!!! I'm thinking that the problem might have been caused by a V4 morph that I was using (pulling it apart and looking at the way it was created, it seems that it was done a little differently than a standard morph).
So, again, thanks for your time and help!  :)
