During testing, the fields (name, address, etc.) in the order form have pre-filled FastSpring information to allow you to test without entering in your own. When your store has been activated and you test using live links, these fields will appear blank (as they would to a customer).
If you are still seeing the FastSpring pre-filled information, you may need to close all web browser windows and start with a fresh session because our information may be cached in your browser. After doing this, if you are still seeing the information, your store is likely still in test/trial mode and you need to open a support ticket to request your store to be activated.
