I just bought the Sims 2 yesterday afternoon and I can't even play it, how lame. I installed this patch (as well as the others Rev A and B), with multiple re-installations (in different locations) all to get a prompt to insert the original disc. Only problem is the disk IS inserted and running. I am running it with BOTH my Powerbook G4 and PowerMac G5, and still getting the same message. Bloody hell!
