[Plugin: ProjectManager] Error deleting a project

I tried to delete a project, and I received the following error (in 1.8.2 and in the latest development version):

Fatal error: Call to undefined method ProjectManager::delProject() in /home/polumetis/webapps/randyhoyt/wp-content/plugins/projectmanager/admin/index.php on line 19
