I've been on the hunt for a few days for the solution to this problem, and everyone is screaming "IT'S YOUR MODZ!" but I don't have any, no downloads, no nothing.  I even went through the process of uninstalling all my eps and the base game, and reinstalled every single one until I found the point of contention.  It's ambitions.  As soon as I install it, I can't click on sims to get them to interact.  It's like clicking on a brick wall, no menu options, nothing.

Any ideas?  I used to have mods before I reinstalled, but I completely removed the entire folder and the entire downloads folder.  No luck to speak of.  I'm at a loss and totally annoyed.  I checked to see if this topic existed elsewhere, but it was a mod-related issue, and this is not.  Unless there are some tricky ghost mods floating around in my game directory...
