If you're just getting a black screen at launch? Sometimes with sound and sometimes with a flashing pointer, but usually just a black screen and nothing else?
Try hitting the windows key and see if it comes up in a window.
I've been having a similar issue since upgrading to windows 10.
I'm not sure what's causing it. When I fired up task manager, it likewise didn't seem to show MEA at least not among the active tasks. I did find it when I scrolled down and looked at the "background processes"
I'm not really sure why windows 10 is doing it, but under windows 8.1 I had no problems.
Under Win10, the game won't run full screen, and just fires up as an idle background task when it's run in full screen mode.
If I hit the windows key, it starts running normally in a window. If I set the game to run in windowed mode, it'll run fine when I relaunch it. If I try to run it full screen, it screws up again.
I'm going to try reinstalling DirectX and see if that does anything.
