CD's in, but the game isn't loading!

[GwannaSauna]

I put in my EaW game disc (disc 1; game's installed) and click 'Play' but the same says "Insert CD/DVD ROM 1" and it's in! What is wrong?!?!? DO I NEED TO UNINSTALL AND INSTALL IT?!?

 

 

Basic Info:

Running on Windows Vista (works fine)

CD is not scratched

Uninstalled mods from the game (STILL doesn't work!!! )

Keep clicking 'Retry' and it still doesn't acknowledge my CD is in the right drive!!!!!!
