The Sims 3 - Unofficial game modification?

Hi, I have all The Sims 3 expansion and stuff packs installed, I installed the last one Into the future when it came out, but when I start the game it says something like:

The Sims 3

It looks like you have installed an unofficial game modification that does not match your current version of The Sims 3. We recommend that you either uninstall these game modifications or get updated versions of them - otherwise you may experience crashes or significant bugs.

It has a Quit and Continue option, I click continue but after a while the game goes into a black screen and then I get a report that Sims has stop working?!

What can I do to fix this problem?

I have no MOD's, CC's just a normally installed game, and this is the first time I experienced something like this.
