Hi Erin,
This is what Symantec has in KB about this error:
Situation:
When you try to open an image in Backup Image Browser, you see the error message "EA39070A: ERR_CORRUPT_BUNDLE 'The internal structure of the PQI file is invalid or unsupported' ."
Solution:
This problem has more than one cause and solution. Follow the instructions that apply your situation:
Cause 1
Typically, this error is reported if the image file is damaged or corrupted. Damage can occur when creating an image over a network if there is significant packet loss during the image creation process. Symantec recommends that you verify images after they are created to ensure their integrity.
Solution 1
Create a new image file in a different location, or create a new image file with a different file name in the same location.
Cause 2
The image file may be fine, but there may be a conflict with spyware detection software, which may be causing the image file to appear to be corrupted.
Solution 2
While using Drive Image, V2i Protector, or Backup Image Browser, disable spyware detection software. - NOTE: it also stands for BESR 6.5
Cause 3
This error can occur if you copy an image file from one FireWire drive to another FireWire drive that is connected to a FireWire expansion card that uses a Via chipset (such as the Kouwell card).
Solution 3
To work around this issue, replace your Via-based FireWire expansion card with a card that uses a non-Via chipset (such as the Adaptec 4300 Fireconnect, which uses a TI chipset).
If these fixes do not correct the problem, run diagnostic tests or switch out your system RAM.
