I've been trying for the past few hours to fix this and nothings working. I even went and downloaded CUSTARD to clean any package and sim3package files I had, just be sure it wasn't something corrupt.
I took out my DC BACKUP files, and deleted them. Cleared my Cache files. Got rid of my mod folder COMPLETELY, ran the game and it worked fine. Placed the mods back in and it didnt work.
I've even tried each town to see if it made a difference, uninstalled and reinstalled, as well as testing sims made with CC and without CC.
Nothing works as long as I have that mods folder in.
And sorry, but if my game ran PERFECTLY with these mods, then I'm not about to take them out because this EP doesn't run it.
I'm so glad I dropped my money on a game that doesn't even fully work...
