Are you able to look at the job under Management Studio/sql server agent/jobs?
-Management Studio/sql server agent/jobs
-Double click the job
-select "steps" from the left window
-double click a step
Could it have more than one step and is being canceled in a step after the table update runs?
Does the user all job steps run under have permissions to everything it/they need.
Do all of the file locations/databases/tables etc.. that the job references still exist?
