Automatic backup

I am trying to set up a task in Windows XP Pro to wake my computer up from hibernation to run a Ghost Backup.  The computer does wake up on time but but no backup is carried out.  The Run line in the task window is "C:\PROGRA~1\NORTON~1\Console\VPROCO~2.EXE" and all the necessary boxes are ticked correctly.  The task is set to run daily at 0200 and a File backup is set in Ghost for the same time.  I have other programs set up using the same username etc that run OK.  Have I gone wrong somewhere?
