Registered customer are entitled to
free upgrades during one year from the date of purchase.
It means that during one year you can download and install the latest
registered versions of ASTRA from our site. If you don't want to
purchase an upgrade, you can use the program forever; it will never
expire, but you won't be able to use the latest version. If you
purchased the software more than one year ago, you are no longer
entitled to free upgrade; however, you can purchase an upgrade to
the latest version at a special, greatly
discounted price, and this upgrade will allow you to have free
upgrades for another year.
