I'm working on the installation for our Seminary computers. Since I didn't have our Accordance username and password, I just skipped the login section, but I put the license code in.
When I came back into to add the username and password, it appeared at first, but as soon as the splash screen disappeared, the login screen disappeared as well. I couldn't get it back, even by clicking on the Easy Install menu item.
As a long time Accordance User, I finally went into the preferences and selected "Suppress Opening Splash" and restarted. This time the login screen stayed up, and I could log in.
