After installing Nintex Workflow for SharePoint SE, The Nintex workflow and forms timers jobs are not displayed in the Job Definitions page in Central Admin.  The only timer job displayed is the Nintex Forms Purge Job. The Nintex dbs are connected, web applications activated, action settings are set, Nintex forms feature activated on all web applications, Nintex workflow is enabled on the sites. I initially installed version 6.0.7.10 and then upgraded to 6.0.9.0 with the same results. The workflows do run but timer jobs are missing. Any assistance/guidance would be greatly appreciated.
