try going in to the sql data base and change your guid in there. start URT and type
\cl_guid
when on each server then, type
\condump guid.txt
change the guid.txt to a new name for each server guid1.txt and so on, the maintainer of the SQL data base should be able to edit
clients
with your new GUID, next time save your URT dir and if your vista/win7 (?) I think you need to get stuff in my documentsettings (?)
