I recently did all the steps it takes in order to install custom content .package files. But when I tried playing my game, it only would let me create a new game. All my sims in the simbin were gone, and my previously saved games were gone too. I exited out and went to my Saves folder for TS3 and all my information was still there... But for whatever reason, I can no longer seem to access my old games. I've also had to reinstall Riverview 3 times now since putting CC in my game. Has anyone else had this problem or have any idea why this may be? Or what I can do to fix the problem? Help would be greatly appreciated, thank you.

If you now remove CC, is the issue fixed? What kind of CC did you install?

No, I removed all the CC and the issue is still there. I installed the monkeyhelper thing to get all the .package files installed and I tried installing some hair/clothing and mods to make potty training faster and game mods like that.
