I installed 1.4x and my mouse stopped working correctly. I haven't played this game since I purchased it sometime back in December. I installed the 1.4x patch. It caused problems so I downloaded SDCentral and installed 1.5. Still mouse problems that make game unplayable. Decided to Uninstall it and reinstall. Caused even worse problems. I remember having issues with installation when I purchased the game but I can't remember what I did to make it not crash (CD is not manufactured correctly). Now everytime I put in the CD and try to install it freezes. I know its not a hardware problem because it does not do this for AOE3, which I have since uninstalled and reinstalled to see if my computer was malfunctioning. Any suggestions? Wow. This forum is about as buggy as the game... Good job Stardock
