Error: unknown class: SuperID=0x200 classID=(0x0, 0x0)

No sure what is going on, but one a file I am working with every time I open the material editor I get this crash error. I'm only using one vray material in the whole scene, 3 omni lights, nothing too special.

It crashes and does not save allow the restore file to be opened.
Any ideas?


Edit: 3ds Max 2012 and Vray 2.10.01

I get this error periodically since switching to 2012 but have not figured out what causes it exactly. Interested to see what it's all about as well.

Do you have Project Manager installed ? It seemed to be a cause for that very error when using slate.

I don't, but I do have File Path Finder Pro from the same guy..... Likely culprit I guess
