Everytime I attempt to log into a multiplayer game using GameArcade, it stops responding. Also, when I attempt Single Player Campaign, it keeps sending me back to the ingame menu and closing itself. I have tried Defragmenting my computer several times, and changed my desktop settings to 16 bit 800x600. I have DirectX 9.0b, Windows XP, Pentum 4, 256 MB of RAM. Please help
