The upgrade files are free for one year after the purchase of a license. After that, you can continue to receive upgrades (and technical support) for another year by paying a fee equal to 30% of the then-current cost of your product license. We continuously improve and add to our offerings and you can probably expect a minor upgrade every 60-90 days (the more products you've licensed, the higher the chance that an upgrade will affect you) and a major upgrade every 6 months.
