[seek-dev] found the problem about DiGir factory service

[Matt Jones]

Hey Bing,

Excellent. Thanks.  As Rod isn't on the project any longer, could you go 
ahead and make the necessary changes to the KU server.  If you don't 
have sufficient access on that machine just let us know and we'll get 
that worked out, but I suspect the account info Rod sent before should work.
