I was having a similar problem with my game. Are you sure about removing all hacks? Some hacks don't apears when you run Sims2Clean Installer. My sugestion is that you run Clean Installer and remove All hacks that shows in it, and after that you run Delphy's Download Organizer, looks for more hacks and also removes them. I did this and I figure that I used to have hacks in my game that I had never heard about! They all came with some houses I had downloaded.
