Stupid Itunes won't Sync to my Ipod

Well I got a new Ipod Classic in November to replace the one that was busted :mad:. Everything was happy and larry between myself and my new Ipod until it decided to stop in the middle of tracks or not play them full stop :mad:. Told me Dad he said restart it so that is what I did and it was fine still had issues with it playing songs but would play the ones I like.

Now my stupid Itunes won't put music on my Ipod and then it decided to delete my songs of my Ipod as well I am not happy, then it says it can't find something :mad:

I have just updated my Ipod to see if that worked no joy it was syncing then it stopped and said it couldn't find a disk but the Ipod never came with a CD I am quite angry as I depend on my Ipod to keep me entertained when going to placement as it is an hour away
