we just installed Netflow Analyzer on Windows Server 2012 r2 with default settings.

After setup has been finished successfully the webseite http://localhost:8080 opens where i should login with Admin/Admin.

The problem is: the default credentials do not work. I tried several times but it does not work. I also started /bin/startdb.bat and received "Could not start postgres database, the post 13310 is in use"

What should i do next?
