I am having this issue after installing Vray1.49. This error shows up when I activate (check-mark) the Vray extension. I am using SketchupPro2015. Any help? Thanks. (Very frustrated with Vray.)

I am having the same issue. I ended purging all materials. Then after I added a component from the 3d warehouse Vray started crashing my file (90MB) again. I deleted the component, purge the materials and it is working fine now. Still, I sent my crashes reports to VRay. An $800 plugging should not wait this long to fix an issue so important.
