Service Unavailable, Please Try Again Later popping up for 2 days now

Okay, so I've been unable to get Unity to let me sign in. I've just updated to Windows 10 and decided to install this about 3 days ago, so I have version 5.2. I can work offline, but I cannot login.

I've allowed Unity through my firewall and my anti-virus. I tried redoing the license file and running it in Compatibility Mode. Also, I am not using a proxy. My drivers are updated and I've tried uninstalling and reinstalling it, but I still can't login and can't use the Asset Store.

What am I doing wrong? :/
