All you need to do is register EW on that new computer using the email and password on the EW account. Once it's registered, if you still don't see the bibles, go to More Available under Scriptures tab and you should see a Download button next to the bibles you purchased. If you don't see the Download button next to those bibles, then you don't have EW registered properly. You can go to Help>Register Products and log out and log back in and make sure you connect to the correct organization that includes the bibles you purchased.
With the Boxcast, we can run a video signal directly from our camera to an HDMI amplified splitter (shown below) that sends the camera signal to our video camera control monitor, AND to the Boxcast encoder at the same time. We send our audio from the Allen and Heath QU-32 mixer using a cable that connects to one of our mix outputs, converts to unbalanced component plugs, and then plugs into the Boxcast. Using the Boxcast webpage and our order of worship for the week, I then schedule our live stream to start automatically on Sunday morning (or Holy Thursday, Good Friday, etc.) to broadcast out on two Facebook pages, our YouTube channel, embedded in our www.fieldsumc.org website, AND the Boxcast app on Roku, Apple TV, and Fire TV (Firestick, etc.).
