Cannot Login - Tried it all

I cannot sign into Articulate 360 anymore. I keep getting two screens, the first being "Sign into Articulate 360 - click to launch your web browser and sign into Articulate 360. This screen will automatically refresh after you sign in" and then I click to sign in and I get "You're being redirected to your web browser to sign in" and nothing happens and there is a button that says "start over" which I click and then it takes me to the first screen. Its an endless loop.

I have tried uninstalling and reinstalling. I have done a manual sign in from the tray. I don't have issues with the system clock, its not a firewall thing. All of a sudden it just doesn't work. Driving me nuts, please help!

 

When I try to open any of the files I get the error below. Please help!
