Sims 3 Launcher won't start

So basically my launcher is being a fool.

I don't know if it has something to do with my computer itself, or the game.
Basically, this one pops up (sorry it's german, but it says that the launcher doesn't work anymore)


I already re-started my computer, but it doesn't work. I even tried to follow a tutorial for this problem, but I realized it's not the actual problem though. Ugh.

Same here..

Does the game work fine if you bypass the launcher? The launcher sometimes just randomly gives up and quits for some people.
