Hi,
I tested on Mac and PC from fresh install and ... same issue on both :'( <br>
But there is a workaround.
First : import a french bible from web : for instance La Bible du Semeur (BDS) from BibleGateway
The exact same error message happens for Cantique des cantiques ...
but clicking ok for the proposed substitution by Cantique is accepted and import continues and terminates successfully.
Second : import the Zefania xml files and no more error happens.
Same behavior on Mac and PC.<br>
This may help to fix the issue.<br>
