DM Albums plugin not working

I've been using DM Albums with no problems whatsoever -quite a straightforward plugin, really - on one site, but a new installation on a new site that's running on the latest Atahualpa version is not working. Upload/gallery creation works, but public page just displays the code, not the album, and I have tried it multiple ways.

If I need to RETROGRADE my installation somehow to the last version of Atahualpa to get this to work, I will, but do not wish to lose all my settings - would there be a simple way of migrating the settings to the old installation? Otherwise I can just go through and make notes, of course.

Hoping there's a simple fix for this or an update that is about to happen, and thanks to anyone who can help. Happy Thanksgiving, too - not expecting answers today!
