I also am having trouble with 10.4.1. I can't import a user bible which I had imported previously (in a previous Accordance version) but since modifying the file I can not now reimport it. The process goes through all the motions correctly to the point where I give it a name. When I click OK it returns to a window headed "Where is the file for the XXX text". In this window I can see the file but it is no longer selectable.
I recently ungraded to Mavericks too. Are there any issues there????
