HI KornelS ,
Welcome to the Community Forums.
Initially registration of your machine for it's base warranty is recommended but is not required.
As per LSC after registration update is done, it would be better to also apply its own update or download the newer version from here. Check your current warranty from warranty lookup tool .
As there may be some inconguency realtime since server synchonization and update would be done first.
You may directly give a call to tech support with a scanned copy of your receipt for manual update as a more direct option.
Update us how it goes.
