Problem: My Library doesn't share on Windows (on BootCamp, Windows Vista and Mac OS X Leopard)

Hello,

I've installed iTunes on Windows Vista, (under BootCamp, on my Macbook).

I want to see my library on my Windows, but it doesn't work.

I already have activated the Home Sharing, and authorized both computers. (I have turned OFF those 2 options and turned ON again, as I read somewhere, but it doesn't work.)

Any ideas?

thank you!
