I have a client whom inquire about the Open-Realty Logo removal.

I read on this page http://www.open-realty.org/download.html that purchasing the Professional Edition would enable the Logo removal.

But the page also mention that there is an annual USD$ 60 fee for Support/Updates.

If my client purchase the Professional Edition, does my client have to pay the annual fee if my client does not require the Support/Update but just to remove Open-Realty Logo?
