Re-enable Pro trial after accidental activation of free version

How do I re-enable the 30 day pro trial? I entered the free activation code before I realised it would limit me to 2 accounts. I’d now like to try the pro version for 30 days to see if it is worth the money, but I can’t get back to the trial!
