If you go to appleid.apple.com are you able to sign in to "manage your account?" Does it show that your appleid/email is verified?
Yes, it is.
Try creating a new user and test it in there.
Apple menu >> system preferences >> users and groups >> click lock put in pw >> click + sign. Create the account. Apple menu >> logout at the bottom. Log into new user.

It reinstalls everything. If you erase the disk, you have to do a backup
Are you using a broadband modem and a wireless router? If so, you could try plugging the modem directly into the computer to see if there is a networking issue with the router. Just turn off wifi during that test and make sure you're online (ie surf in safari first).
It starts and immediately freezes. I can't do anything with it but force quit.
