I had a problem with it, Whenever i would try to open the HyperShade it would crash the system (no questions asked) and I tried lot´s of stuff (including delete prefs) know what I had to do?

I formatted the comp, and didn´t install all the special packs (only the second which came with the disk) nor security patches, turns out one of them in some weird way was interfering with Maya.

That was my experience.
