Al: Thanks for responding. I'm using the MD-BT01 and making the connection from the registration to bring up the PDF in SongBook. Before I was able to reply to your post I somehow managed to get the link working again and as a result do not have the
quote from the error message.
At the time when the error occurred and I could not link any of the previously linked files, I was attempting to link a registration to the pdf of Fawlty Towers , the theme of the British television show. Somewhere in that time period things went off track. Pardon the pun but that's when all became "Faulty". So, if the problem returns I will note the error. Thanks again. Reg
