I received the registry key with e-mail but the key doesn't work. I copied it into the register-screen clicked the button and the register screen vanished without any comment or failure-message.After restarting RC the register screen asked again for the key. I read in another post that there might be a problem with the minus sign in the ID number I have not included this in the second mail I wrote to the register-bot because with my first try (when I included the - sign) I received a mail that the bot wouldn't be able to process the request because there were alpha signs in the ID string. Please help I'm eager to getting started!!

i put the minus sign into your key request email, and it will be processed again in 25 minutesjd

Got it. Thanks a lot for very fast response.
