After ''Changing Permissions'' for the latest update, my game will not open

[juicyjayla420]

I have The Sims 3. I also have The Sims 3 Late Night Expansion Pack, which I installed after I installed the base game (The Sims 3). As most may know, that changes the icon of your game to the Late Night icon, therefore changing the entire game because it also gives you a whole new town and everything. Anyways, I hadn't played my game in a while and naturally there was a new update which I needed to have in oder to play. Yesterday I proceeded to download two different times and my internet was being crappy (so I assumed) because it took forever and never finished, both times. So I manually forced the download to quit and tired again today. It was actually working today and a option came up to ''Change Permissions'' and so I did, the bar reached 100% and everything closed. My game will not launch since then and I have no idea if it updated, or what happened. If anyone has any thoughts or comments, please let me know. I have already contacted EA and they said they are researching and calling me back. 

Ty for your time,

Jayla

Try a clean reinstall following the instructions here: http://simswiki.info/wiki.php?title=Game_Help:TS3_Uninstall and here: http://answers.ea.com/t5/The-Sims-3/Help-Guide-All-in-one-fix-except-hardware-issues-PC-only/m-p/734... where it says Delete game installers

Manually delete everything if above method does not work: https://help.ea.com/article/manually-uninstalling-the-sims-3

Make sure everything Sims is gone from your computer before reinstalling

If the game still shows in your Uninstaller Menu afterwards, you can use CCleaner to get rid of those.
