I have spent more than a week trying to do a clean install of my Sims 3 games. I have all the expansion packs, and I am using direct downloads through Origin. I installed the base game, then patched it to 1.31.118. Then I installed my EPs and SPs in order. When I got to Outdoor Living Stuff, an error message popped up that said, "Game Validation Error." And something about the game being more recent than expected. It asked me if I wanted to continue, so I did. The same message popped up for Generations. I am not installing Pets at this time because I was experiencing the horrible freezing bug, which is why I started a clean install in the first place. Anyways, when I went to play my game, it simply did not open. The launcher opened, but nothing would happen when I clicked play. It was working after I installed World Adventures b/c I checked to make sure, so I am guessing this game validation error was the problem.
I talked to EA Customer Support through the chat, and so far, they have not really helped, and in fact, now I have to re-download my games because of their advice. I have been elevated to the next level of support.
BUT do any of you know what to do about this game validation error? I would really appreciate your help!
