[SOLVED] The issue was caused by a missing .dll D3DCOMPLILER_43.DLL Download and Install Direct X Restart the Computer Run Steam Run Assetto Corsa It will try and do a first time update and re-install Direct X. Don't let it, 'X' out. Assetto Corsa will open up shortly afterward (5sec) Now it works ======================ORIGINAL ISSUE==================== So, My PC took a crap this afternoon after IMSA GT3 race at Laguna. All of my skin files that I created for all of you are now gone forever. So, I went out and bought all new PC parts, water-cooled this time. Just got it all built up and running. I installed Assetto Corsa and ran it up. I picked the BMW M4 and then the Red Bull Ring. The loading screen comes up as if it's waiting for the car and track to load. Then it goes right back to the selection screen for the car and track. I doubt this is a Windows 10 issue since that is what I had on my old PC. I check my resolution and it is 1920 x 1080 like it's supposed to be. I even tried the 'Force 32-Bit' check box in the 'General Settings'. Please help.
