Problems after installing 1.67 update

I've spent hours now trying to fix this problem. I've had that kind of problem before but then it somehow got fixed itself (i honestly don't know how) after i did'nt play the game for months. I played again yesterday and had lots of fun. Now today i thought i would finally make that update and download some official free stuff. Everyhing worked fine except the game. Now after the intro video there's just a blank main menu. I can't choose city, saved game etc. I've already searched for a solution from this forum (and from all kind of other forums) but i did not understand anything and as i've tryed so many things already then i honestly need some kind of step by step instructions how to fix that crap.
I can say that ultimate fix did nothing (it seamed to be kind of out of date????) I also tryed some kind of re-setting factory settings but it did totally nothing. It even did't react they ways that intructions told to do.
Do i really have to uninstall everyhing and just re-install the game? If so then how can i save previous game? So i don't need to start my whole game from the beginning.

Hello,

It sounds like there have been two possible problem for you. The most likely one is, one of those free stuff(CCs) are corrupted and just messed your game.

It's really easy to understand if it's the problem. Please go to your documents folder and rename your "Sims 3" file whatever you want, for example Sims 3try.
Then open the game again let it create the documents file. Just check the game if the problem continues. 
If it does, it means problem is about something else than your CCs. If it works without any problem, that means you have downloaded come corrupted files and ruined your game. And probably not adding those newly downloaded files to the game will solve the problem.

Please try this and let us know the result. Good luck! 

Well that re-naming The Sims 3 never worked so probably tehere is sitll problem with the new stuff. So i should just uninstall and delete all that stuff?

Could at last somebody teach me how to save game saves from uninstalling so i dont need to start whole game again???

Just move your entire Sims 3 folder from documents somewhere else (from C:\Users\Your username\Documents\Electronic Arts\The Sims 3 if you're on Windows 7), that way it can't get removed through uninstall. Once you reinstall your game, place it back where it belongs and that's it really.
