Bri423 Please instead do a clean uninstall and reinstall of the game and the EA App, as described in the accepted solution of this thread (for a different issue, but the process is the same):
[CURRENT ISSUE] Sims 4 DLC shows as installed, won't load in-game | EA Forums - 11831673
If that doesn't help, please try playing again in a clean boot in the new Windows account, as you could in theory have multiple issues. The clean uninstall/reinstall may change the outcome of the clean boot.
puzzlezaddict I give up. The more I try to fix it, the more messed up it gets. Now I can't uninstall it after uninstalling/reinstalling 3 times... Instead of coming out with new packs, why not fix what is broken already? I was stoked about the new pack. What is the point if I can't even play? Thank you for trying to help, but I'm no IT person...I'll try again in a few months...
