Hi, I've just bought the medieval 2 expansion pack, but I can't get the game to run on my P.C. All the system requirements(I think) are correct. I first taught it was the disk, brought it back,got a new one. Still the same. The icon for the game doesn't even appear in the drive. I've tried an external drive but its the same outcome. I think its the graphics card, but I'm unsure. Requirements for the game: (My system) * Windows 2000/XP/Vista (XP) * Celeron 1.5 GHz Pentium 4 of equivalent AMD processor (2.4 GHz recommended) (2.80 GHz Intel Pentium 4) * 512 MB RAM (1.0 GB recommended) (1024 mb ram) * 12.0 GB free hard disk space (40.0 GB) * 100% DirectX 9.0c compatible 16-bit sound card with latest drivers * DirectX 9.0c (included) (Directx 9.0) * 128 MB hardware accelerated video card with Shader 1 support and the latest drivers. Must be 100% DirectX 9.0c compatible. (256 MB NVIDIA GeForce 7300, ATI Radeon X1600, or greater recommended) ( (RADEON X300 Series 128mb) * Internet connection required for multiplayer (Broadband) * 1024×768 display resolution (Display resolution 1680*1050) Any help???? Thanks.
