Ok so yesterday I logged into my account on my computer and clicked itunes to open it. Instead of going to my library it said It cannot find my music library and told me to locate it. I clicked "Locate" and it went to my finder. We have had an external drive for the the past 6 months and I had been storing all my itunes on the external drive AND on the normal hard drive. So when I clicked the locate button, I chose the itunes library in my external library. Now my library is setup like it was about 2 years ago, complete with ipod nano games, playlist, and songs I have deleted. when I click a song to play it says "Cannot locate file." If i go into the finder and find the normal hard drive, and go into itunes media, I can double click the songs and play the songs in itunes. I tried deleting all the songs from the external drive from my library and replacing them with the ones from the internal hard drive but I found out that only about a 5th of my songs are on the internal drive, Everything else is on the external.
