Hello everybody. This is my first post. Im having the same problem. Ive recently downloaded skp 2017 and vray 3.4 on my new msi laptop. It worked fine for a couple of days but all of a sudden the render wont start. As kilua24 said... it only shows render history settings and the vray frame buffer stays stuck on 0%.
Im quite desperate now.. wont find any answer on the internet. This happens even on an empty new model.
