I have searched everywhere and cannot find help for this.  My computer still shows the Sims 2 and Uni installed but will not let me uninstall and will not let me play.  Keeps telling me problem with Sims 2 reinstall, but when you put the disc in nothing happens.  Almost like the computer thinks it is there, but it is not.  Please someone help as I want to reinstall all my games, but I cannot do a thing.
