Sims 3 Pets Loading Issue

Please help.

I installed the Sims 3 Pets edition off this website. I installed it, found out where to find the en_EULA file and the Origin Setup* file, and fixed by myself the insert disc problem. This game works like a champ until I tried to load a save file, for it either takes eternity to load or barely loads at all. I even tried creating a new data, but still no dice. I know you've all been piled with Sims 3: Pets problems, but this will help a lot.

Hello,

Please open your launcher and hover your mouse over the base game icon in the lower-left corner of the screen. What version does it show?

Besides that, do you have any Custom Content and/or Mods?
