Was Working, Now Not Working SmoothGallery Plugin

For about a year the WordPress SmoothGallery Plugin was working fine. However it was noticed today that it was not working but fairly certain that it was working fine as of last week. Any ideas on what could have caused this plugin to stop working? You can see the big white space where the gallery loads on this page: https://bwpurpose.org/portfolio/schools/greater-brunswick-charter-school/ & I deactivated all of the other plugins to see if there was a conflict, but still the gallery is not working. Anyone else run into this issue?
