Classifieds Update breaks my site

I did the update for Classifies from the WPMU auto updater. Update went fine, but it broke the functionality.

When I click on one of the categories set up for my Classifieds I got this:

Fatal error: Call to a member function get_options() on a non-object in /home/umha/public_html/wp-content/plugins/classifieds/ui-front/general/loop-taxonomy.php on line 23

I deleted the new version of the plugin and reinstalled the old one and it's working again now.
