BESR backup - Application error stops and restarts the BESR service.

I have BESR 8.5 on a windows 2003 SP2 server.
Everyday, the scheduled back up face this problem.
Here is the description from the event log:

Does this error happen consistently during a backup? In other words, can you easily dupicate the error?

Next Wed or Thurs, BESR 8.5.5 wil be released. This might resolve the issue. However, before you ugrade, because of the nature of this error, you should uninstall BESR, reboot the server, and install 8.5.5. This will flush the drivers and ensure that the VProSvc.exe is newly installed.

Send me a private message and I can send you the download credentials before then from where you can download the update.

It happended twice ,and the automatic - scheduled increamental back up failed. So I ran a base back up manually, and since then didn't see this problem happening again, running smoothly for last 4 days!
