Hi EmileeAllene,
I am not sure what to say. Although I do have a few tips to try. If you haven't tried these already.
--- Turn Off Interactive Loading Screens - Go to Options (...) Select the gear tab, which is the General Settings, at the bottom of the menu uncheck the box labelled Interactive Loading Screens
--- Delete the Game Cache Files
socialCache.package, Sims3Logs.xml, simCompositorCache.package, scriptCache.package, ompositorCache.package, and CasPartCache.package
Also delete everything except Ccmerged.package file in the DCBackup folder. (Delete the contents of the folder, not the folder itself) -- Be sure to leave Ccmerged.package alone.
--> Documents > Electronic Arts > The Sims 3 > DCBackup
--- Sims 3 Factory Reset (HowTo)
Move your Sims 3 folder to the desktop or some where safe, and rename it something like Sims 3 Current. You won't loose your files, like saved games or game options. It's all still there in the folder on your desktop or some where safe. Just don't delete anything.
Click the Sims 3 icon to create a new Sims 3 folder.
Go To: ----> My Documents > Electronic Arts > The Sims 3
If you want to continue to play your previous game-saves, go into the Sims 3 folder that you backed up and copy over your game saves, files and such over to the new game to see if that helps.
[This is different from a total-game reinstall - This just sets the game back to factory default.]
Hope this helps,
MrsFlynn
