Just wondering if anyone might be able to help me figure out what is causing the following:

The 4 files that are failing have been modified since the last time they were successfully backed up.  None of the other .wpd files have been modified and they are all backing up fine.  Other files have been modified(.xls, .doc etc) and they are still backing up fine.  There are 2 accounts on the windows box, both are admin.  Any ideas/suggestions,  it's getting a little frustrating.  Thanks in advance
