Changing the location to /Users/bobembry/Documents/Kardnote/kardnote.knlib didn't help.
I tried deleting everything and starting over. Every time I relaunch I can't edit or open previously created notes.
I was able to crash KardNote twice.

Nothing has worked so far.
BTW: my problem started after the most recent version upgrade.
