<p>Hi Isaac.</p>
<p>I'm guessing the number you were asked for is the CCLI number? CCLI is an organisation that allows churches to display copyrighted worship song lyrics in return for an annual fee. The church then gets a number which should be entered here. However if you don't have one and only use your own or public domain songs then you can leave it blank and openlp will continue to work fine.</p>
<p>As for the error you get at start up, this is a common problem. The solution is to go into the settings and select both a theme on the first tab, and set the display monitor correctly on the second tab. Then OK the settings and restart openlp. All should then work fine.</p>
