Silent Angel Z1

[Leif]

I use a Silent Angel Z1 from thunderdata for my Digital Music Server
http://www.thunder-data.com/z1

This product comes with MinimServer 0.8 pre-installed.
I would like to upgrade to a fully licensed version of MinimServer 2
But the website of SilentAngel Z1 says:
Because of MinimServer 0.8 license change (see MinimServer web site: https://minimserver.com)， newly installation MinimServer on Z1 will not be able to work. Existing installation of MinimServer can continue to use with some limitation.

I do not understand these lines.
I have emailed thunder-data, and they told me, they had to ask MinimServer.

My question: Am I the only one in this world who wants to run MinimServer 2 on a SilentAngerl Z1 ?
