I'm pleased things are starting to work for you. Your learning curve will become less steep the more you work with the program.

You raised several issues in this post, and I'll deal with this one:

Somebody suggested I check to ensure that realtracks and realdrums are enabled. How and where do I do this please?

Right-click on a radio button for an instrument (third row down), for example, guitar. You will see the option, Add/Remove Real Tracks. From that, you may choose from the real tracks that you have purchased. Since using Real Tracks requires time to regenerate the song each time you press Play or make a change in the chords or song structure, you normally want to make sure the song is 'done' before substituting the Real Track instrument for a MIDI one. You can add a Real Track on any of the instrument tracks (not drums; that's for Real Drums), and it does not have to be related to the instrument name. For example, you could put a trumpet on the guitar track. When a track uses a Real Track instrument, the name of the track will turn Green.
