Can anyone tell me this: I tried to upgrade from winme to win2000 pro. I have games on my system, but win2kpro said it can't run them. If I continue with the installation, and get all the service paks, will my games all work? Also, it told me I won't be able to use ms works 6.0. What's up with that? Can I upgrade and get to do games and ms works?
