There was a problem with the sign in process.
We are seeing this issue in our district as well.
Same problem here. It let me start yesterday, but I got a system error and lost all the entries while attempting to register the first of my three kids.
This morning, I get the same 'Sign In Problem' message you just posted for all my kids and can't move forward at all.
