Hello, I'm a big fan of air simulaters like x-plane. Yesterday, I had installed demo version of x-plane11. But when I operated x-plane, the message: x-plane is totally out of memory.....pops up and it just stops working again and again. I installed x-plane in my 32g usb drive, and there is about 12g space. Also, I have already deleted the preference folder in output folder but I can't still operate x-plane11. What should I do?
