Crash to Desktop

Hello all. I have been playing the Sims 3 for more than a year now. I have always used G4TW fixes, it works perfect for everything. I had the base game and all expansions except for Sweet Treats, Master Suite, and Diesel stuff. The last expansion I installed and fixed was Supernatural several months ago. It has been working fine but I decided to try Seasons and I ran into some trouble. I followed the directions to a T, updated/patched my game, applied all the cracks in the right folders, and applied the master fix.

Now for some reason when I try to load saved files it gives me an error message and crashes. Yet what's confusing is I am able to create a new game and play just fine, but when I boot the game and try to load even the new save files it just crashes out to the desktop.

Any help would be greatly appreciated, been fighting it about a week with no luck.

Do you have mods/cc?

If you do, backup/rename your Documents/Electronic Arts/The Sims 3 folder, which will generate a new one for you. Your game will be blank when you reenter, but try moving one of your saved families that crashes the game into the "Saves" section within your new folder, and see if it works okay in-game. If it does, then you probably have some mod/cc that is causing you trouble.

You can try re-adding the mods back one by one to see which one it is.

I feel so silly. I don't know why it didn't occur to me sooner to check my mods. I decided to take a simpler route and just remove the entire mods folder from my documents. When I did it loaded the entire game just fine (good to know I cracked the game correctly after all). I'm in the process of weeding out the problem mods so thanks for the suggestion

Well, it turns out that it was Twallan's Master Controller causing the crashes... which is rather disheartening because I used that one like crazy. I'm currently looking for an updated version of that mod which hopefully will play nicely with Seasons.

At any rate my game is back to working flawlessly

The newest version that Twallan has come out with is right there.
