I installed sims and it worked fine. I borrowed some expansion packs and installed Unleashed. Before the installation completed, there was an error message. I can't remember what it said, but after that, sims wasn't installed on my computer. When I tried to install it again, everything worked fine, but when the installation actually started, it didn't do anything. It didn't read the cd, and the only way I could close the screen was with ctrl+alt+delete. I couldn't find any way to install it. The first time I installed it was with the original cd I borrowed from someone. I burned the cd and used it to play. Someone help!!
