Z10 and MoonReader - howto handle in Calibre?

Hi,
I'm a calibre user with both a Nook Color and a BlackBerry Z10. On the Z10 I'm using Moon+ Reader Pro 1.4 (sideloaded) as my current ebook reader. It's pretty good actually, though I should see about upgrading to a newer release.

In any case, has anyone got Calibre working properly with the BB Z10 to install books so that Moon+ Reader can find them properly? I've been poking at this, but I can't seem to make it work properly, or consistently.

Thanks,
John
