Try deleting the localthumbcache.package and the onlinethumbnailcache in the The Sims 4 folder.
The game should make those again when you restart the game.

i have removed all my mods, tray folders and the onlinethumbnail files and nothing has worked .... im just so sad and flustrated
Try resetting your user files as described in the factory reset described in this post: http://answers.ea.com/t5/The-Sims-4/FAQ-Troubleshooting-Steps-amp-Known-Issues/m-p/3621199
You won't loose anything. Just make sure to not delete any files and make a backup.
After renaming, repair your game by right clicking on the game in Origin.
Put just your save game back and try again.
If it still works, you can start putting stuff back.
The rest does not need putting back, cause they are mostly cache files that recreate or log files that are not needed for the game.
