I don't see why you shouldn't be able to edit the models in the current release once you've installed it.
Hmm, i`ve tried installing it a couple of times and I still get the same errors.

Well, iv`e tried pcs2 to open a number of the models and the error states that the models are not valid models.
Modelview, higher limits says that they have an invalid file header.
Maybe someone else can try to open a few and see if they get the same resualts.
Eh.. the place I was trying to upload... err, my computer froze up when trying to use them.. I take it that site wasn't designed for ~1GB files, despite claiming to have no filesize limit... I'll find a place eventually, though. :/
Ok, i`ll wait as long as it takes, and thanks for your efforts jr2
