Another Itunes/ipod Problem

[237SJ]

A while ago I had a problem with iTunes. Itunes couldn`t find my songs from my flash drive. While that problem was ongoing, I tried to synch my ipod Classic but it only synched the purchased music. The original problem was solved so fine - everything`s in the library and playable. In the meantime I have bought a new iPod Classic but when I synched it, it only synched the music from my CDs. I think this is because it only synches changes from last time and it thinks the purchased music is on my new iPod. So the situation I have is that I have purchased music on my old iPod (which I`m going to get rid of) and my own music from my CDs on the new one. How do I get all of the music on my new iPod? I know you can de-authorise the computer but do I need to d-authorise the old iPod?

Forget that - I`ve sorted it.
