I currently have ZA 7 and the license runs out in a month or so and am looking at purchasing a new year. If I just purchase another year without renewing, can I use the new key without a major hassle and get a new year? Also, something I read indicates that the year starts on the purchase date but I would like to go ahead and purchase and only use the new key for the next year when my current subscription expires. Is this possible?
