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.
Note: If your period of free updates is not over, you don't need new license keys to use new JFormDesigner releases. Simply install the latest version of JFormDesigner and use it.
To verify that you are eligible to upgrade, enter your purchase ID and the e-mail address used in your previous purchase. You can find them in the JFormDesigner License dialog or in your license key file.
If you made more than one purchase in the past, you can receive Volume Discounts when upgrading them at once. Then enter a comma separated list of purchase IDs, but only one e-mail address.
