FIRST : I use a theme "Life" which I installed few months ago, so I don't think this information will be usefull here.
The plugin suddently stopped working. I really have no clue what could have happenned... WP3.5 was already running for a few days without affecting the gallery.
THATS WAS THE BEST GALLERY PLUGIN EVER !! Sniffff
I've done what all of us would have done, deactivate, delete the plugins (all of them) reinstall only the carousel and still not working... I really have no clue what happenned.
BE CAREFUL : The first post image opens with a lightbox included in the theme. The carousel affects all others post images. (supposed to) try on any other picture of any post...
