Rick,
I posted this in another message (see below). You will get "card error" until all four of these are met.
The control panel will not recognize the Conductor until you have created:
1) at least one *.seq and/or *.mp3 file on the compact flash (CF) card,
2) created a password, which will create a password.dat file on the CF card,
3) create at least one show, which will create a file *.sho on the CF card, and
4) schedule a show to run, which will create a playlist.dat file on the CF card.
All four of these must be met before the control panel will see the Conductor.
Note:
1) All files names must be 8 characters or less.
2) Do not ever delete or rename any files on the compact flash card. If you do you will have to reformat the CF card and copy your files back to the CF card before the Conductor will play your show(s).
