*Rage* Stupid Game.dat Runtime Error

Installed an old game I used to play before, LOTR Battle For Middle-Earth. First one, not second one. But all I get is error messages when starting it. *Put in the game disc* Honestly WTF for some BS that is. What did I install it from?!? 

 

Second problem is a game.dat runtime error. Sometimes it pops up before the game has finished loading, other times I can play for hours without nothing happening... Well I could twice. Now the game won't ****ing start and it is making me mad! 

 

On the other hand, maybe I should use the time to finish some newer games that I have, but still in their respective wrapping *looks at Split Second, Grid, Resistance 2* and other unfinished games *MGS , Dirt 2, AC Brotherhood, Forza 3, N3*
