I am trying to update to Air Hockey 1.1.11 on my 16GB iPod Touch rev 2 running iPod software 2.2. I do not know how to tell what version of Air Hockey is already installed. I am using the App Store app on the iPod to get the update. I tap "FREE" and then "INSTALL" and then I put in my Apple ID password. I'm taken back to the home screen. The Air Hockey icon gets a "Loading..." bar on it, and then a popup message appears: "This discounted price is only available to customers who own a previous version of the item. To purchase this item at full price, click Buy." Then I can either Cancel or Buy. I have been clicking Cancel. What happens when I click Buy? Is something corrupted? Do I have to re-download the app?
Thanks,
Eric
