@pomk786 That's the issue: your patch level is so old, it predates the mods setup that you're using. (The way to install mods was changed in I think 2010.) The fastest way to get to patch 1.67 is by running the Super Patch, an EA-made tool that does all the work at once. You can download it here, under "Cumulative Base Game Super Patcher":

It's a good idea to move your Sims 3 user data folder out of Documents\Electronic Arts first, run the patch, start the game once to make sure it's working, then transfer any content you want to keep from the old folder to the new one. Here's a complete list of everything you'll find in that folder:

If the mods still don't work, just download a fresh copy of the Mods Framework, add it to the new user data folder, and delete the cache files again.
