Hi Nicola Loncar, I don't have  a way to reply to your response but this question was asked before. I am trying to purchase the extended plugin so I may sync with google calendar.  I want to purchase via a credit card but the option does not work.  I also tried to purchase by using my paypal account but that too does not work. How may I pay for the extended plugin given the options on the website don't work. Thanks for your reply.
