1. DO NOT try to access Learning Center (LC) using a cell phone. LC doesn't typically work well in Android/iOS environment.
2. Use Firefox , Chrome , Opera or Edge for a browser. LC isn't a fan of Internet Explorer or Safari.
3. Make sure that you're actually *in* the LC course. Once logged in, move the mouse to the top of the browser window, hover over [COURSES] and then click on [MY COURSES]. Then you can actually select the referee course and get into the classroom. The modules are found under the [ASSIGNMENTS] button.
4. If videos aren't playing correctly, try using a private / incognito browser window. Sometimes item in the browser's cache gets in the way.
