Lic Error Message

Hello together,

the lic-support told me to open a ticket @ tech support and they told me to ask here:

I get the error message, that I am "Licensed for home use only"
I don't know, why the system thinks, that my family is an enterprise.
The Lic is all right.
Is it possible, that there is a problem with my network settings
I have a
* DMZ 192.168.123.0/24 with a webserver (fix IP)
* LAN 172.16.123.0/24 DHCP Range with 15 adresses in use

Does anyone has an idea?

regards
Achim.Z.
