How old are the programs?
I have recently purchased several games for my Windows XP computer, installed them correctly, then when attempting to open the exe file the cursor simply blinks for a second and then nothing happens. This has happened with three games that I recently purchased, however Unreal Tournament 2004 came out with a patch that fixed the problem. Is there a compatability issue that I may have missed or maybe some drivers that I should install? Any help is greatly appreciated. Thanks.
