iPod Aweful on Windows XP

I don’t really listen to my iPod anymore. Why? Because it will not sync. I can’t sync, it won’t recognize my iPod then when I try to sync it tells me

“the ipod cannot be synced the required file cannot be found”

So, what to do, buy a new one, or take it in to get fixed? ‘l’ll scrap iTunes and see what other software I can use.
