I've had a Puzzdate (update from Puzz ) regarding the RVC code - I am now able to Play the Game
If anybody has RVC problems, contact Puzz with all of your details (Ramisis number, Key number, description of problem, etc), and he will mark your Ramisis as 'Unlocked' so that you are able to access the game. He didn't mention whether to contact him by PM or email, so it might be worth doing both.
He is with the Electronics guy today, so hopefully they will get to the root of this problem shortly.
