A much needed help. :) [SOLVED]

Hello,
I've had a problem with running my Sims 3 (+ All expansions except Katy Perry [ew]).
I've tried the Ultimate Fix, I've tried it all. Nothing works. I still get this error:

 

Any idea what went wrong and how I can fix it?

Thanks a lot.

Thanks for replying.
I have no mods, only base clean game+expansions.

EDIT: I reinstalled everything and followed the amazing guide on how to install, used the fix and it works perfectly with all my expansions.
Thank you!

Nope. Thank you!
