Unreliable Product and company is making my situation worse

After a Trend Technician remotely fixed my Trend issue; I now cannot make backups using Windows.

Does anyone have a simple fix for the following error/backup failure message:

"Windows backup failed to create the shared protection point on the source volume (0x8078006B)

"Additional information:

"The shadow copy provider had an unexpected error while trying to process the specific operation (0x8004230F)"
