I'm afraid I don't understand Maurice. You can't just copy to the next folder, the procedure for blank cards is explained clearly in 5.01, if you follow the step by step it will work (you appear to have left a step out).
I don't understand how you can sucessfully perform 8.04 and get 'file is empty' message since the whole card will have been correctly overwritten. And something is wrong if you cannot transmit with Song Manager. If you can provide some detail I can try and provide a solution.

Thomas's excellent implementation of my Card Reader idea is still somewhat in beta form as far as the install goes, and with the pressure of work I have not yet got around to writing the help file.
