The answer is here on the Forums but I don't remember what it is
I don't use iTunes so I really don't completly pay attention.
If I remember right the New version of iTunes is the Problem.
I'm guessing you could do one of two things.
1st. thing you could do is downgrade versions of LW.
2nd. thing you could do is downgrade versions of iTunes.
There are several members that use iTunes here that have far more advise than I.
Hope this Helps.
