I am sorry you are having these issues. My best guess is that that version is not compatible with the latest Nvidia drivers. Can you pls test this theory by trying the DEMO version at https://render.otoy.com/forum/viewtopic.php?f=44&t=71080.I installed 4.02.1.44. I tried pulling down the 2018.1.0 but it won't authenticate because I don't have a subscription.
My license is for the non subscription version.
