I am having a little trouble playing my game. I downloaded d fend yesterday and was finally able to play my old game of Warcraft 2. I played for a bit but then exited out of everything. I went to go play it today but something pops up and says I need to have the disc in the computer for it to work.

I never took the disc out in the first place and even though I do have the game inside the computer, I still get something that says I need to put it back in.

Is this something you can help me with?
I'm not sure if I am even doing this correctly or not

Thanks.
