3dsMax craches when opening material library

My 3dsmax randomly crashes when I open the material library, its doesnt happen all the time but atleast once every few hours and its a bit annoying. I have attached my minidum file can someone please check what the error is ?

Hi, sorry for the inconvenience. This is a known issue, but happens so rarely that we do not yet fully understand what is causing it. Can you please tell me what kind of license you own and what your registered email address is? (here or via PM)
I should be able to provide a solution then.
