Sims4 won't launch

AG8291​  Are you trying to launch the game from its desktop shortcut, and if so, does it work if you launch from within your EA App game library instead?  Make sure the App has fully loaded before trying.

Yea they know. 
If you have an older version of your game like the one before the market place update. I recommend copying the bin files and pasting them over the new ones until they iron out these problems.  That is what I did and if  steam or ea app makes you update after that just do it again about the update. and you should be just fine.
