Keeps Crashing and It's Making me Crazy!

You may want to clear (delete) the five cache files on the top level of your TS3 user game folder in Documents if you don't already routinely do this before doing any thing drastic. It may help or not, but it's an easy process to test first and it would certainly need to be done anyway if you are going to replace the entire Mods folder with a new clean one.

Then, assuming you had a working game prior, perhaps remove only that which you just recently added (and clear the caches again) to see if that helps.

Problem solved. It was the poses I downloaded today. Now I have to choose. Damn it!

Easiest way to tell is to copy and past the mod folder to a safe place such as the desktop, then delete it from the sims 3 folder.Launch the game.If it launches fine, then its something in your mod folder.

At that point, you'll want to download an empty folder.

Which you can get there.

Then slowly add your CC back(groups of 2 or 3) until it starts crashing again.Once you hit a spot where it crashes, go back to your mod folder and delete one cc, then relaunch until the game stops crashing.

I just found it easier to start with a clean folder and put my mods back in a little at a time when I was having a weird graphics issue instead of trying to delete 1 by 1.I usually clean my caches after each gameplay.i ended up having some weird alien plant override mod in my game causing my plants to be Florescent pink ? have no clue where it came from but let’s say I got so worried About a dying graphics card I wrote to aced for a repair slip LOL
