Database Error after last Update

After the last auto update I get this database error when trying to access Studio.
Fatal error: Uncaught Error: Class 'BxTemplAcl' not found in /home/com/public_html/inc/classes/BxDolAcl.php:129 Stack trace: #0 /home/com/public_html/modules/boonex/timeline/classes/BxTimelineTemplate.php(37): BxDolAcl::getInstance() #1 /home/com/public_html/inc/classes/BxDolModule.php(71): BxTimelineTemplate->__construct(Object(BxTimelineConfig), Object(BxTimelineDb)) #2 /home/com/public_html/modules/base/general/classes/BxBaseModGeneralModule.php(25): BxDolModule->__construct(Array) #3 /home/com/public_html/modules/base/notifications/classes/BxBaseModNotificationsModule.php(40): BxBaseModGeneralModule->__construct(Array) #4 /home/com/public_html/modules/boonex/timeline/classes/BxTimelineModule.php(74): BxBaseModNotificationsModule->__construct(Array) #5 /home/com/public_html/inc/classes/BxDolModule.php(102): BxTimelineModule->__construct(Array) #6 /home/com/public_html/inc/classes/BxDolPreloader.php(84): BxDolModule::getInstance('bx_timeline') #7 /home/com/public_html/inc/cla in /home/com/public_html/inc/classes/BxDolAcl.php on line 129
