TCP error code 10013, how to solve?
at first of all, the cmc docs are not very enlightening, just contain setup steps / screenshots (everybody knows how to run a setup) but further details or a troubleshooting section is missing *thumbs down*.
Well, let's go - the cmc setup runs successfully, without any errors, then I've set up a new site under the iis manager at port 81:

The Management Server (Serivce) is running without any errors:

Management Server Administration is configured on port 4502:

clientaccesspolicy.xml:

The site starts perfectly, but the first abnormal thing is visible in the background of the following screenshot, it seems that the words "Trial" and "Activated" are drawn to the same position, the next row contains the same problem.
However, if I try to activate the license, I will get an error message: "... Could not connect to net.tcp://domain:4502/ManagementService. ...":

The port range 4502-4534 is opened and the configured domains are at every configs the same.
Don't know what to do here, I guess it's an novastor "insider" affair and it's not solvable for "outsiders".
What a glorious doc, smile benignly:

The logs:
C:\Program Files\NovaStor\NovaBACKUP Central Management Console\WebRoot\log.txt is empty
C:\Program Files\NovaStor\NovaBACKUP Central Management Console\Service\Logs\trace.log does not conatins any errors
The environment:
Windows Server 2008
MSSQL Server 2008 R2
IIS 7
Novastor Storage Server 12 + cmc
Thanks for any help and greetings from munich, germany.
