Can't setup a new account.

I don't know what it is trying to tell me, it's just saying "Objektreferensen har inte angetts till en instans av ett objekt."
If I give the wrong details, it just says wrong password.
I'm on Windows 10, and it looks like I already have the microsoftsoftware installed.

Steam Login Error

Objektreferensen har inte angetts till en instans av ett objekt.

That's what it looks like.

Removing my mobile authenticator fixed THAT problem. Now the next problem is it says it can't add my account.
