I can't seem to find info on this as is your game now HOWEVER in the future if and when you uninstall / reinstall:
Take your brand new reinstalled game,
Go to "Computer / C / Program Files (x86) / Maxis / Thesims / UserData" (this is my path on windows 7 64 bit , your's may be a different OS)
just backup the "Userdata" file to CD-R disc, flashdrive, whatever backup method you use.
"Userdata" is neighborhood 1, the others are in order 2-8.
Save them all. NEXT time you want to Re-Set without having to uninstall, simply remove your current "Userdata" (or neighborhoods 2 through 8, whichever you want to replace, any or all), and Replace with the Backed up brand new one you saved.
I've done it and can verify it works.
