abistasiasims Great, so at least the problem is contained to your main account. There are a few players with the same issue, and I'm still trying to figure out where exactly this data is stored, but in the interim, you can play in the new account if you want. For any saves or other user data you want to transfer, just drop it in C:\Users\Public, which is accessible from any account. Grab it from there and put it in the Sims 3 folder in your new account, or just transfer over the entire Sims 3 folder.
If you want to look around a bit, go back to your main account, download Piriform's CCleaner (the free version is fine), and search for files with sims 3 and sims3 (without the space). You'd only want to remove files you didn't recognize and that were in your main account, as in, something that the new account wouldn't be using. I don't know exactly what you'll find, but if this isn't a task you'd like to deal with, let me know and I'll test it myself later. You can also simply document what you find, not deleting it, and list it here for us to go over.
I just tried to use the CCleaner to search, however, I don't think I did it right. I used the duplicate files finder and then scrolled trying to find anything with those in the name. I didn't find anything, but if I did this wrong, let me know and I can do it another way!
