Hi all,
I'm putting this down in case someone else experiences the problem. OSS has now resolved the issue.
It basically required a simple parameter in the NWBC options file to include Allow Temporary Connections.
File content should look something like this:
<SingleOptions>
<ActiveConnection>SAPERT</ActiveConnection>
<ShowSystemInfo>True</ShowSystemInfo>
<AllowTemporaryConnections>true</AllowTemporaryConnections>
</SingleOptions>
Problem solved, another crisis averted!
Regards,
Liam
