I have just installed the Legendary 727 and have a problem with the TCE

When I open the TCE,I have only 2 tabs - Testuring and Configuration - is this correct?

More importantly, when I try to save a configuration, I get the message:

"Legendary 727-100 not found"

Note I have re-installed twice and used the Flight 1 tool to ensure the registry key is correct.  I have also checked the KB on the CS Site

V grateful for any help.
