Unable to login via softphone

While trying to test a solution for a customer's answer today, I discovered that I was unable to login via my RingCentral Softphone on Mac using any of my accounts (production or sandbox). I wanted to share an experience that I had today in case other people ran into this issue, what the conditions for the issue are, and how to resolve it:

The scenario: I had my RingCentral soft phone installed, and it was configured to use my Development (Sandbox) account of RingCentral (as documented here: Earlier in the day, I installed the most recent update (as recommended) to the software. When I tried to login later, I was unable to do so (no matter what account I tried using, or if I modified/removed the config.ini which allowed me to use my RC-Sandbox account). I kept receiving an error message "Invalid Credentials". I tried using the SSO (Single Sign-On), but that failed too.

The fix: I simply uninstalled the RingCentral for Mac software from my MBP (Move the Application to the trash), and downloaded the latest version from the web ( and re-installed. Then all was well with the world and I was back to developing.

Hope this helps if you run into the same issue.
