Sims 2 Ultimate Collection keeps crashing at loading screen

@N3WB0RN1R0NMAN , first of all you need to be really careful about what CC and mods you download for the game. There is a limit on how much CC the game can handle (I think it's 4GB but I'm not sure). 

Have a couple of questions first before I offer some suggestions.

1) Did the game start and play fine before you added the new CC?

2) What OS version are you playing on?

3) Did you update your Graphics Rule.sgr file?

Thanks!

@N3WB0RN1R0NMAN , thanks for the information. 

It sounds like something is possibly corrupt in your game, but don't worry. You don't need to reinstall the game at this point. I do want you to do the the following.

1) Go to Documents and locate the EA Games folder. Inside this you should see a folder called "Sims 2". Move (do not copy or create a shortcut) this folder to your Desktop. Don't worry your game will create a new one which is what we want it to do. Your saved games will be safe on your Desktop at this point.

2) Start up your game and see if all the proper screens come up. Hopefully they will as we are starting a "new vanilla game" at this point. None of your saves will be present at this time. 

3) Next play for a while and see if anything out of the ordinary occurs at this time. This is a good time to troubleshoot before adding back any CC or mods you want to play with. 

Let me know what happens after you do this at this point. And we'll go from there. 🙂

@N3WB0RN1R0NMAN , Yay! So we fixed whatever the game was doing weird before. (Remember this fix if the game ever starts acting up again). Also before you play, go into your Documents folder > EA Games > Sims 2 and delete the Groups.cache and Accessories.cache. These files can be come corrupt really quickly and deleting them doesn't hurt the game. 

Ok, so next step is to add in a few pieces of CC. I'd only add about 10 to 20 pieces at a time so you can test the game and see if any of those pieces cause your game to do weird things. I wouldn't add more than about 2GB to 4GB of CC and would stick to the lower end as the game tends to have problems running a lot of CC. If you like to add back your saves from the original folder, let me know and I'll give you more info.

We're doing this one step at a time to keep your game running.
