4) Paste the desktop copy into the original file location (C:\\Program Files\Electronic Arts\The Sims 3 Seasons\Game\Bin) and select copy and replace.
Open up the game and the pop-up should have left, and the game should work.
If there are any other problems please don't be afraid to ask.
Also, please reply letting us know if it worked or not so we can rename this post as solved.
