Well, you're gonna have to give a bit more info than that...
Do you have the game disk inserted? In the US version of the game, this is disk 2.
Do you have a copied version of the cd? Copied games don't work.
Do you have the latest patch installed? If not, do so right now! It's version 1.44, you can find it in the support section of the beyond divinity site.
If the above fails, post your specs.
