When you click the [Demo] button in the StylePicker, it will either play a local .wma demo if one exists, or it will play an online demo.

After you click on the [Demo] button and hear nothing, go to the Chord Sheet and type the word "Log" followed by <enter> (or go to Help | Utilities...). This will bring up the log file showing how it tried to play the demo. It either tried to play a demo locally or online, and it either succeeded or failed.

Here is an example of a demo - can you download and play it?
