You need to edit the config file with a plain-text editor that respects Unix / Mac line endings: a line feed with no carriage return (Windows usually adds a carriage return). NotePad++ is a good free one that will do the trick.
If you can't fix your config file, email it to me —
sawyer@sfwriter.com — and I'll try to fix it for you and email it back.
And it's not a long-press menu choice to export annotations. Rather, from an open book, you hit the Notes button (the one that looks like a dog-eared lined page) at the bottom right of the screen when you tap to bring up the menus.
From that screen, you'll see two tabs: "Table of Contents" and "Annotations." Select "Annotations," then from the "..." menu at upper right, select "Export Annotations."
