If you are a customer of JFormDesigner and your period of free updates is over (see License dialog), then you can upgrade to the latest version at a substantial discount.
To verify that you are eligible to upgrade, enter your order/purchase ID and the e-mail address used in your previous order. You can find them in the JFormDesigner License dialog or in your license key.
If you made more than one order in the past, you can receive Volume Discounts when upgrading them at once. Then enter a comma separated list of order/purchase IDs, but only one e-mail address.
