I have just opened an iTunes account.
I copied a load of old MP3 file that I had bought and loaded these into my iTunes. All fine so far.
However, when I try to SYNC my playlist , I get the error;
"Some of the items in the iTunes library including "xxxxx" could not be copied to the iPhone because they could not be found"
Therefore I am unable to transfer my legitimately bought music onto my iPhone. (Legitimately bought but not from iTunes).
