Storyline 360 -Logged In, But Still Prompts for Login

I could use some help with this, as well. I just opened SL360 and 3 times during my simple work to import a video, update the player settings and preview/save, I was prompted that I had to log into Articulate 360 to continue...and given a button to log in.

I clicked the button and a window displayed saying I was being redirected to my web browser to sign in. No redirection occurred. The window has a button to "Start Over", which I had no choice but to click, since there was no obvious way to exit the window otherwise.

The window then changed to display a lock icon and a "Sign In" button...still no redirect to my browser. So I clicked "Sign In".

(BTW, I should mention that after the first time through this process, I did get signed in and still had the browser window open , with my profile icon displayed and a "sign out" option...so I was signed in during each subsequent launch.)

At different points I had a "Cancel" or "Exit" option, which took me completely out of SL360...while still being signed in online.

If it helps, I originally launched SL360 from a Start Menu icon. And just now, I click the Articulate 360 icon in the Start Menu, and again am being prompted to sign in. And, still getting a "redirect" message which doesn't occur, a "Start Over" button, followed by the "Sign In" button. Yet, I'm still signed in, which is how I'm able to post this message.

What am I missing?

Thanks,

George
