Is Rise down? Can't access

Hi Richard, 

You can have Articulate 360 installed on two machines to access the installed programs such as Storyline, Studio, and Replay. For more info on this take a look at our Terms of Service. 

For Rise, you should be able to log in across browsers and computers, since it's entirely web-based. I'm often logged in on 3-4 different browsers as I test in Chrome, Safari, Firefox (Mac and Windows where applicable). 

If you run into a similar issue again, can you also try accessing the site from a private/incognito window? That'll help confirm there isn't an issue with caching your previous login or session.
