License for 5.12 is lost when pc name changed !

Hello together,

i had to rename my computers name.

So at the next time starting RS 5.12 i get a license error message.
When i changed back to the old name the license is still ok.

What is that ??? :rage:
I hate this node locked license ! - I will my old style floating license !!! :grinning:

How can i change the pc name ? - And how can i move my license to an other (new) pc ?

Thanks to all.
Klaus
