Narrative:

Controller called aeronautical radio to climb aircraft to cross 59W at FL370. Aeronautical radio phone operator was not able to send clearance to aeronautical radio, radio operator. I believe this was due to installation of a new computer system (interface problem). Flight then progressed to go west at FL350 and was climbed. No other aircraft involved.
