gallery disappeared after update!

I’m sorry that happened, but there is no reason they could have been deleted unless you uninstalled the plugin. I even tested the update on two live sites before launching it with no problems.

Is the gallery still showing, just not the albums?

Take a look:

It’s so weird! The galleries and albums are still there when accessing the settings…

Have you checked to be sure your id is correct for the [utubevideo] shortcode? Also have you changed your wp_prefix at any point after installing the plugin?
