Ac is one of my favorite sims. Two days ago I downloaded a Bentley sim and it did not have any sound ..Then it advertised a sound fix so i downloaded it and installed and right away lost all my sounds in AC. I was forced to Remove the documents file for AC, then uninstall AC completely thru steam and re-install . Now I am ok again although it took forever to reinstall. Be careful with Mods. They are great but can sometimes cause unknown [roblems.
