Purchased plugin, but don't know how to unlock full version

Hi Maros,

I like your work. I just bought the plugin, but I don’t know how to unlock it. Would you mind show me how to do? ( I think I was being stupid, and bought it with guest account… Please give me a set of account and PW so I can login, thanks )

Thank you
