Im getting the 'application has crashed and will now terminate ' message

So, when i bought and installed the new legacy collection i had no issues at first ( except for my child sim disappearing after i had just made them and loaded into a house). I have tried 6 times to load in that same house today and now it keeps coming up with that message. I have installed the 4gb patch in hopes that worked and im still having issues. I even uninstalled and reinstalled the game and it still comes up with the message. 

I have just 'repaired' the sims 2 legacy within the EA App so I will try again and see if that works. 

Anyways... does anyone know how to fix this xoxo
