Nothing wrong with my PC I am afraid. It is only Maya 8.5 that has the issue. I was running Vista Ultimate, and it was only the two issues i found.
The MR one is talked about by Autodesk, and they have stated MR is not supported by Vista at all and dont plan too. The ma file problem is not one for the mb files.
