Finally got everything installed after about 18 hours

I was having problems also what I did was a clean install then install everything, however do not install the cracks until you come up to the 70's, 80's, 90's..........then start installing the cracks, also if you are having problems with updates, look in the folder for the support then select update and then update your game, I was finally able to get my sims connected.........however for some reason when I installed into the future and started to play it.  I get the error message you have an unofficial mod but it was working.

The error message is because of your mod that already outdated.
Perhaps you should check which mod need to be update or remove before any problem happen ~

I had no mod's installed..........only the game, the stuff packs, and the expansions

Then clearly you either have the outdated crack. Please repeat steps 2-4 of this guide again: https://games4theworld.forumotion.com/t1171-must-read-how-to-install-the-sims-3-correctly.
