I'm attempting to run the game on Windows 7, but when I try to start it it goes straight to a black screen. My cursor is still visible and I can still move it, but I can't Alt-Tab, Alt-Enter or Ctrl-Alt-Del out; I just have to wait for a while and then it goes straight back to my desktop. I tried uninstalling and reinstalling, then tried downloading again, but it's been the same every time.
