He is asking to update from 10.55 to 11.00 - so NO downgrade! And so also NO risk to loose any setting.

If you have set up your F5 for automatic update - no action needed - will updated in the next day(s). If youre in "hurry" - try to connect to a PC and run GE - probably the updated will run immediately. And again - due it's an updated - no setting will change.
