[Plugin: Pinnion Plugin] Error message when using Pinnion Widget

Also, on the Pinnion widget itself (as well as the pop-up when I try to add it to a post) it reads “Invalid Username or Password.” I set up the account and am logged in and have not made any changes. I was able to create and save the Pinnion just fine.
