Hi all i downloaded a couple of free games from itunes the other day and then i go to the applications tab in the ipod tick the games i want then click apply. it then says syncing and then it says installing but then when i go into the menu of the ipod there is nothing there just wondering if i need to update it or something it says its is up to software version 2.2 Also the ipod menu screen doesn't show up in itunes so i can't arrange any of them.
