UMDS error "Loading DTN BDB"

["BobR" <bobrabcd@xxxxxxxxxxxxx>]

Question for anyone experienced with the UMDS, perhaps a developer can
answer it:

In your use of the UMDS did you ever run into an error when putting the UMDS
online to Start Realtime Collection?  The error occurs when "Loading DTN
BDB" and says "UServer illegal Op - shutdown".

Thanks for any insight on this.  Why does it happen and what is the
solution?  Can the UMDS be reinstalled from the same initial .exe download?
When doing so the reinstall recognizes that there was a previous
installation.  It appears that the UMDS will go online and receive packets
from DTN but no longer will process any of the data.  It won't even auto
fill the index or futures lists.
