To purchase a license from your device, Tap on the Activate button on the main screen of TouchDown. This will open a window where you select the last option titled “I want to purchase a license”. When you do this, it will take you to the Google Play Store, to the product titled “Exchange by TouchDown Key”. You can follow the prompts in the Google Play Store to purchase that product. Once purchased, install the license product and run it once.
After you run “Exchange by TouchDown Key”, your main TouchDown program will be activated and will stay active as long as you have the license installed on the device.
NOTE: When you purchase a license from the device through the Google Play Store, you do not receive a serial number. This is because the Exchange by TouchDown Key contains your serial number and is designed to be portable without having to remember the serial number.
