Resolved 17.5 - License - "Parent key not provided"

[futureweb]

Hey there,
currently I have a 10 Domain License on one of my Plesk 17.5 Servers.
Want to replace it by a newly bought unlimited Domain License ... but every time I try to submit the Activation Code I get: "Parent key not provided" Error ...
Any ideas on that?
thx, bye from Austria

ok ... dumb failure on my side ... was trying to activate some included Feature with it's own Activation Code ...
