BE SR2010 Recover Files from corrupted Image

Hello,
i'am using Symantec BESR 2010 for MS SBS 2003.
Having big trouple at the moment..
During the nightly full backup the system drive of the server crashed (aprox. 15 minutes before backoup would be done ;-(
I was able to restore the system drive with an older image, but i would need a couple of files and foldes from the corrupted image.
Whe i try to open the image with the recovry point browser the system displays the following error message:
"Error ED800012 The Internal Structure of the image file (Last File Frame) is invalid damaged or unsupported"
Is there any chance to view and recover some of the files and folders which are in the corrupted image?

Regards
Ralf
