Is it possible to uninstall SP1 for BESR 8.5?

I realize SP1 for BESR 8.5 brought significant bug fixes but this issue where the BESR GUI hangs when there is an RDX/RD1000 drive present in the computer is causing us quite a bit of problems. For the sake of information, this is Windows Small Business Server 2003.

First of all, we worked around the issue by accessing the backup drive through a shared folder. That created a new issue where a handle is kept open to the RDX drive which prevents the eject functionality from working.

We came up with a work-around for this ejection issue where we would use a pre-script to create a share on the drive and a post-script to delete the share but the post-script that deletes the share sends BESR into pandemonium. Here's the single error we logged in the Windows Event Viewer at 5:39AM this morning when the backup finished:
