iTunes won't open following moving folder after reinstall I have MacBook Pro mc700 with OS X Yosemite installed.
A couple of weeks ago, I decided to format my HDD and install a fresh version of Yosemite, so I copied all contents of my iTunes folder into an external hard disk and installed the OS X. Now when I copy the iTunes folder back into my MacBook my iTunes app can't recognize it and so nothing happens. I know probably I've done something wrong about "just copying" the iTunes folder but I would really appreciate it if anyone could help me to save my old iTunes library.
Thanks.
Hold alt (option) while opening iTunes, a window will open allowing you to select your iTunes library.

Make sure you're iTunes is up to date as well.
