Ever since the update to version 7 of iTunes when playing music from my iPod on iTunes I get the "The iPod [iPod Name] cannot be updated. The requested file is in use." error every 5 minutes or so. I have the latest software version and the issue happens both on my 5G 30 GB video and my wifes 5G 2GB Nano. Unfortunately these are both out of warranty. Anyone have a suggestion on this? I upgraded to Vers 7.1 of iTunes with the same results.
