So, I downloaded the 2.0 software, and when I try to download apps from the store off my touch, I get the message that tells me to sign in iTunes, and when I connect my iPod to my computer I can download it (something similar to that). What do I do? I already signed in, and it still gives me the same message when I try to download an app from the Touch.
