Why i can't syncronize adress book on local path with .mab extension, it throws an error and it looks like that syncronizer search only for .sqlite extension???

This review is for a previous version of the add-on (3.3). 

Version 2.x of the add-on runs up to TB 68 and uses .mab files. Version 3.x of the add-on runs on TB 78 and later and uses .sqlite files. If you upgrade from TB68 to TB78 all addressbooks are converted from .mab to .sqlite automatically. But you have to use the addon and upload to local/remote/imap the new .sqlite files manually once!
