Purchased game not on Mac or iPod.

I purchased Infinity Blade on my iPod this morning, along with NFS Hot Pursuit. I made a mistake by syncing my iPod while downloading Infinity Blade And now it doesn't show up on my iPod or my Mac. Then I opened my iTunes on my iPod and it asked for my password, so I entered it but nothing changed. I know It charged me though as I saw my iTunes balance drop the listed amount, so I was wondering if anyone knew of a way I could get this app back. I won't be able to get back to my Mac before tomorrow evening so if it is possible to get it on my iPod again without my Mac I would love it, but I understand if that isn't possible. =P

Thanks for all help! =D
