No connection to the sims 3 store

I am not able to use the Sims 3 Online functions, because my game won't connect to the Sims 3 Store. I tried to change my password, changed my email and reinstalled the game multiple times now, but nothing solved the problem. I cannot download the stuff I bought in the store, because I can't log into my account in the Sims 3 Launcher. The box, where the profilpicture and username used to be stays empty when I log in. When I try to log in when I'm in the sims 3 menu, where you select the family u want to play, my game freezes while connecting. My game works fine when I play offline, but I want to play with the items I spent my money on.
