DPM Writer "Non-Retryable" Error with LiveVault (Autonomy) Backups

I haven't been able to run a backup for some time now, and after troubleshooting with the LiveVault (Autonomy) techs, we see that the error is with the DPM Writer ... error below :

Writer name: 'DPM Writer'
   Writer Id: {0074a271-4f24-43e0-9ec7-28a44189cb80}
   Writer Instance Id: {975711c7-87e7-438a-83be-d1691c576db1}
   State: [7] Failed
   Last error: Non-retryable error

I then ran the following VSS Fix :

net start "COM+ Event System"

The fix gets the DPM Writer to a "No Error" state, but once I run the backup, it fails, and the DPM Writer goes to the "Non-Retryable Error" again.

Any help would be greatly appreciated so I can get a current off-site backup.

Thanks!
