Dear all, I just downloaded the new version 9.0.3 and from reading all the reviews, I guess it was a mistake. Too late!! Anyways, Whenever I try to open Itunes, I get a msg that says "This copy of itunes is corrupted or is not installed correctly. Please renistall itunes" So, what should I do? How do i reinstall? Will I loose all my music !! And how can I downgrade to 9.0.2? PLEASE HELP !!
