Hi David. Welcome to justanswer.

David, are you using Windows or Mac computer?
Once you click this link below(CLICK HERE)A file will automatically get downloaded. Check your download section, a file named ELSINORE.SCREENCONNECT will be present. Just open that file so that I can connect to your computer.
If you are not able to locate the file, then just click Ctrl J from your keyboard and it (Elsinore.screenconnect) will be the first file listed. Just open that file.
