Re: Sims 4 error: Failed to launch game

This started appearing after I uploaded a new batch of mods (made sure they were all up to date) and when I tried looking up what it was I saw a few things talking about a 'scratch' file, and there was something like that in saves, which I hadn't seen before, I deleted it and opened up the game again, this time it did open normally but it was a new game.

Then there was a new EA file on Documents, I copy pasted the saves and mods from the old one into the new one and now it won't let me open again ;(

I don't really know what to do, I'm pretty new to this.
