Hi Vitali,
Your payment of US$23.95 gives you early access to Tickstory along with any updates until August 31st. Other terms of the software license do not change. We unfortunately cannot guarantee updates indefinitely for the fee we are charging which is why this limitation is specified. If there is sufficient uptake of licenses, then this would mean we could provide on-going updates for a longer period. The structure is designed to benefit all – if users participate, then we can continue to provide updates for you. If not, we will revisit the fee while ensuring that licensed users somehow benefit from their early adoption (aside from the obvious advantage of getting to use the latest software right now).
