Create a Job, and then use a file trigger as your event trigger. Save the job. Open the Job...click on the Trigger and without doing anything hit OK...thats when i get the email saying inactivated...and after trying again...i can recreate also with a custom time trigger. I am on version 6.1.3 and have had this scenario in previous releases...just never asked the question. You can create any type of tasks within the job.
