Here is the script I use, obviously your ReportID would be different, but the table and field names should be the same
update s
set s.status = 1
--select s.status
from scheduleattr s
where s.reportid in (12042, 54333)
This runs every hour just prior to my schedule kicking off to ensure it is enabled. I tried setting up new schedules but that never worked. I do have the latest build and have never went to back to test it to see if it still happens because it is so light weght to me it doesn't matter.
