The first couple times I ran Elite Force, it ran perfectly. Now it's mostly fine, but as soon as I start it up the text "NO DC" appears in the upper left corner of the screen and nothing will make it go away. I have no idea what it means or what caused it to appear. It's a minor issue, but pretty distracting. I've changed absolutely nothing from the first times I played, so there's literally no reason there should suddenly be a problem now.

Awesome, the very first solution in the article you linked seems to have fixed it. Thanks very much!
