NSW 12 - Speed Disk error

This is my version: Norton SystemWorks 2009 Version: 12.0.1    Build: 1

 

Every Wednesday at 10:30 pm I receive an error from Speed Disk - The first error says it can't find a description for the error of 1020.

 

Then about 3 minutes later this message is in Event Viewer: Faulting application NOPDB.exe, version 19.1.0.9, faulting module sdntdrv.dll, version 19.0.0.8, fault address 0x000055e0.
This shows as an application error with an event id of 1000.

 

I used to have Speed Disk scheduled on several days for different disks, but sometime back I removed the checkmark from Enable Schedule on all of my disks.  What's really strange is that I must have at some point been running the Speed Disk at 10:30pm (because other days used to be scheduled at 10:30 pm), but what shows up grayed out for the Disk it used to scan on Wednesday was set for 12:00 am.

 

Anyone have any ideas about this?

 

Thanks.
