I'm running this as administrator on Windows 10/64 and it just ends up with a blank screen after choosing to load a project or start a new one. After it sitting blank for a while, if I click on the screen Windows pops up with a box asking if I want to close the program or wait.
I've tried it with compatibility mode for Windows 7, and still get the same problem. I have 16GB RAM and I'm using a GeForce 1070 video card.
Anyone else have problems like this? I'd love to play around with this engine.
