I had the problem with previous Nvidia drivers, but not only with Vue, but C4D, even Firefox, if I wasn't doing anything with the computer, the drivers  would randomly crash after some time (randomly, because it happened sometimes only). And to thicken the mystery it only happened on my new workstation with Win 7 X64 and a GT560 Ti. It never happened on my other Win 7 X64 machine (laptop), with a GT 240M.

Haven't worked much yet on the new machine to see if the new drivers fixed the problem, was hoping it would, now I know it won't...
