Crash Everytime I import my .fbx

I am currently trying to import a umber of my characters they are all .fbx files and they import but the second they finish I get this popup and my program shuts down. I cant seem to get any of my characters to import

I need help asap

I had that problem when saving the default (newest) version of FBX out of 3ds Max.
When I exported as an older version of FBX, it worked. I think 2013 was the version that worked?
