So I've put off upgrading to the latest iTunes for fear it would mess things up, finally did it and guess what? Yep, it's messed things up! Not only will it not sync to my iPod now but it has lost over 2000 songs. I've spent the past year and a half putting almost 9000 songs on and making loads of playlists and it's a bit gutting. All the songs and playlists are still on my iPod but not in the iTunes and I can't get it to sync at all so can't add anything. It does recognise my iPod when I plug it in and it does still charge but it keeps asking me to log in to authenticate my iPod which I do but then the sync doesn't happen. Is there an easy way to fix this? Any help greatly appreciated.
