Hey, Louie, hi...
I have installed many a game in my ME with no trouble. But then I play off-line strategy games. If you are playing on-line games, you usually need a pretty up-to-date CPU to handle things. Your note that you have a '56k computer' probably means that you have a 56k modem, but doesn't say anything about your computer's processor speed and amount of RAM available.
If you go to your desktop, find your 'My Computer' icon and right-click on it, you will see a 'System Properties' window. In the lower right portion of it should be the computer specs that will tell you if your machine has the power to handle the games you want to install.
For example, mine shows 'Dell OPTIPLEX GX260 Intel Pentium 4 kCPU 2.54 GHz, 260,088 KB RAM'. Most games nowadays want at least a 1.5 Gig processor and at least 125 megs of RAM, which my box exceeds, so I would have no trouble installing a game. You may have less than the game wants you to have.
There was an old 'Doonesbury' comic strip in which one character tried to load a program, and the computer displayed a farcical message from that program to the effect that the computer wasn't powerful enough to handle it, and insulted the user. Sometimes we feel that's what's happening to us. Hope you get better results.
