Strange crash

I'm using SR 0.97.8 with max design 2011 64bit under windows 7 64bit.

When i start SR and change some settings it's all ok, but when i close SR and press F10 and load a vray preset (one i've made my own) max crash.

You think it's a SR problem or max one? It only happens after using and closing SR.

Thanks

p.s. i closed and reopened max and after choosing the same preset max crash another time. So i think that SR corrupt it.
