With your XLGL purchase, you will receive a one-year subsription to the XLGL Update Service. This service will give you access to all updates for one year.
You may renew this service at any time to add time to the subscription and continue having access to all updates.
The current price for the renewal is computed from your number of licenses. The base price is 249$ for the XLGL Personal Edition (or your first 2 licenses in case of volume licensing),
then 100$ per additional licenses. For example, if you own 5 licenses, the renewal cost will be 549$ (249$ for the first 2 licenses, then 3 X 100$ for the additional licenses).
