i have no idea. i never installed those "keys" myself.
in fact, i didn't even know about the "keys" before this problem started popping up.
this installation was migrated (using plesk migration) from a previous plesk 9.x installation on another server, when we moved to the 1and1 cloud.
i never had those "Subject: Parallels Panel key update deferral notification" emails until last week, when i upgraded from 10.3 to 10.4.4.
let me know what i should do to manually resolve the issue.
i assume i am not the only one with this sort of problem. the email we receive is very cryptic ("an error occurred" but no idea of what error!).
it is possible that at one point, the "gameserver" product was installed on our old plesk 9.x server. that may explain why there is a key, and the key got migrated when we did the migration.
