Hi John,
Here is the response from Development:
I think this relates to user defined relationships.
Subset stores these in an xml file in %appdata%\Grid-Tools with a name that is the same as the connection profile name.
So, if there is a new connection or if Subset is on another machine, these relationships will not be seen.
Copy the contents of the original xml file into the new one to see the previously saved rules.
Richard
Cheers!
