Minimserver2 functionality

[Melco Man]

Today I installed Melco Firmware 3.92b on my N1ZH. Then I downloaded Minimserver. Then I went to the http://192 etc etc to configure minimserver. I paid £28 for a full license.
However, I did not receive a confirmation email and, despite having minimserver selected on the front panel of the melco, there is no sign of the library on the app I am using.
I have used minimserver in the past and always liked it. I stopped using it for a while because I was waiting for it to be built in to the melco.
In addition, my mac will not let me download minimwatch - something to do with security, despite me trying to overrride this in settings.
