I was just recently able to load itunes 10.6.3 to my new pc with Windows 7 64 bit. When I enter itunes, I can see all of my music etc. I have purchased and loaded onto the itunes library when I was using windows XP. However, when I try to start any song in the list I get a message that " The song ........ can not be used because the original file can not be found. Would you klike to locate it? " When I click to locate it, it is nowhere to be found. Any ideas on what to do from Here?
