latest scope v5 registration

[ARCADIOS]

i already had installed the previous scope pci v5 and over it, i installed the the latest december v5.
i used the previous keyfile though, before soniccore emailed me the new one, and it seems ok.

is it necessary to reinstall using the latest keyfile i received now?
do i miss something?

i have just installed over old installation, everything works fine,
also no keyfile needed, just first time when i have installed scope 5.
