Itunes Library main vs shared I recently moved by itunes library from my pc to an external hard drive and updated to itunes 11.0.  After doing this, when I click on my music I can see two separate libraries.  One is just under Library as music.  Then there is a second one listed below that says Shared Library and refers to the external hard drive.  Some of the songs from albums are missing in the main libary but are present on the Shared Library.   Do I need both of these libraries and if so is there a way to update the main library to get these missing songs from the shared library?
Okay this is what I would recommend.Follow the steps:


Clear Out your iTunes Library completely
Copy the contents from your hard disk to a place on your Computer
Add the folder from your computer to your iTunes Library and you will get back your old  arrangement of songs. 


Hope this helps!
