I'm trying to backup my logbook on CD. When I try this I get a message saying the following:

This zipfile is part of a multidisk zipfile. Please insert the last disk of the set.

I'm not sure what disk I'm supposed to insert for this. When I hit OK after this, I get a message telling me to restart Logbook Pro and try again.

I don't get these messages when I back up to a floppy.

Any suggestions?

Also, do you have any idea of approximately how many logbook entries can fit on a single floppy. I'm up to about 1800 entries and I'm only halfway done.
