serious error

Hey there,

I've downloaded sims 3 and all the expansions. I've installed them all and it works fine until I try to load a saved file. Every time I try to load a save I get the "serious error" message. I've tried everything I could find but nothing seems to help.

(maybe) useful info:

Way of installing (maybe I am doing something wrong here?)
1 base game (did not apply crack)
2 town life stuff (did not apply crack)
3 generations (did not apply crack)
4 pets(fixed) (did not apply crack)
5 world adventures (changed SKU to "2") (did not apply crack) [ignored the updating thing]
6 high end loft stuff (did not apply crack)
7 ambitions (did not apply crack)
8 fast lane stuff (did not apply crack)
9 late night (did not apply crack) [ignoring the uninstalling part]
10 outdoor living stuff (changed SKU to "1") (did not apply crack) [ignoring the updating thing]

11 Since everything was updated to the most recent version (launcher confirms it), I took the files from the #crack/Pets & Town Life Stuff & Generations from the ultimate fix and copied and replaced it with the files in the sims 3 base folder.

This way I'm getting the serious error message when I try to load a saved world or game, every time.

I tried to apply the "error trap mod", but that doesn't help, reinstalling does work either.

Also I'm not using any CC.

So does anyone know how to fix this?

Thanks for the quick reply, unfortunately I still get the same error. I managed to load a save once but after saving it again, the "serious error blablabla" error shows up. Restarting it doesn't seem to help after that.
