CMC Crystal repors are in paused state

Hi,

I am using BOXI 3.1 sp7

How can i Seee error message for  Paused report ?

I have written query as

SELECT sI_NAME,SI_KIND,SI_ID FROM CI_INFOOBJECTS WHERE

SI_RECURRING = 1 AND  SI_SCHEDULE_STATUS =8

and i have seen reports in instance manager.

I need to know why reports have been paused?
