I don't know if it's a versioning problem. Most of his stuff seems to be made for 5 or 6. (I'm using an older version myself, so I haven't run into any problems.) One would expect some degree of backwards-compatability, but that's not always the case.

BTW Sparrowhawke3d has an account here at Renderosity, so float him a message. He's fairly helpful and would have a better answer on problems with his plugins than I would.
