I downloaded games using the application store from another laptop and itunes. Now I am downloading music from my imac desktop. Music download was successful. But afterwards all the downloaded games won't work. What seems to be problem. I already tried downloading again the applications. But everytime I put songs to my ipod touch 2g the downloaded application games won't work. Please help. Can I download music w/o destroying my previously downloaded application games from a different itunes/laptop?
