Can't think of why You'd have Problems.
Get a hold of DirectX 8.1.
Fingers Crossed

Every time I try to run Allied Assault, the game never advances past the first pop-up (the one with the allied assault logo above the picture of the guys in the higgins boat heading towards the beach). It says that there is an error with one of my files. I have re-installed the game since first encountering this problem and it did nothing. I'm running a P4 2ghz, with 256 mb ram and a GForce 2 32 mb vid. card. Both of the demo's ran fine so i am guessing that i have a corrupt installation file or something. If any of u have had this problem and know how to fix it PLEASE let me know how, i think this is one of the best games ever (RTCW is just a little too far fetched for me) and i am dying to play the game. Thanks.
