Are you using a shortcut to access the game?

Yes, everyone does. Make sure the 86x version and not the 64x, because the 64x version doesn't work for shortcutting, even if it doesn't work from crashing the game.The 86x version is much better for reasons and you can use the shortcut by copying the file with the game on it, then click once, right click, then click to "send to ->DESKTOP-shortcut". And when in shortcut, click twice the thing and it should work.
Hope it helps. :)
