I have a very nice computer I use with IL2 Great Battles WWII flight sim.  My machine has a GTX 2080ti GPU and an Intel i7-8086K CPU @ 4.00GHz, 32GB RAM, 500GB HDD plus a 3TB hard drive.  I bought X-Plane 11 a couple weeks ago and an Archer III add-on a/c from JustFly.  I had gobs of HDD space and loaded just Europe and the USA maps.  When I started x-plane 11 it said something about an error in instillation and when I tried to "fly" with my Vive Pro headset the headset started blacking out and freezing the program.   
Then I went back to my main flight sim, IL2 where I fly missions with an online squadron.  I then found you'd ruined my IL2 as well as it "blacked out" the VR and froze just like in X-Plane 11.  I removed X-Plane and the add-on aircraft.  No help.  Now I've removed and reloaded Steam, Steam VR, IL2, the Vive Pro software and reloaded and installed everything and still my computer freezes and the VR blacks out when I try to use IL2 in VR.
X-Plane 11 broke my computer.  It's useless now for VR flying!  
I spent thousands of dollars for this computer for one purpose, to fly flight sims in VR.  I only have mocrosoft office and IL2  flight sim on it.  Now it's useless to me.
I removed xplanne so I have no LOG.TXT file to be able to even send in my question.
There's no phone # for tech support.
WTF?  Your program killed my computer!
