See this migrate iTunes library post and copy it over from your old computer,

The same problem as you had. Details of the experience I had may help. After installing the latest iTunes, two months ago, I found that all the songs showed, as did the albums. On approaching a song in any playlist, the screen showed an exlamation point(mark in UK) to the Left of the song name, and asked me if I would like to look for it. I'm sure this can be done, but with 11,000+ songs I will have no time to eat. I am going to approach this very carefully. A year or two ago, after a similar road-block, I re-assembled 500+ songs into their Playlists over many hours, but on this occasion would very much prefer a quicker, ultra-secure solution...glad, though, that you have fought your way through successsfully. The Repair Disk suggestion from mallory623 is tempting.

Will i get my music back? I am sync-ing my iphone when suddenly all my music was deleted. My music is almost 900 songs. How can i retrieve them all?

Thank you! TuringTest2 This completely solved my problem.  Afraid we were going to be rebuilding a lot of playlists, but your simple step by step instructions turned a potential multi day project into 3 minutes! 

You're welcome.

Thank you, so much for your assistance with this.  It worked perfectly.  Even though my library only showed music from 9/2013, once I updated the software, another 1288 songs were added.  I didn't miss a single note of the music.  If you want to run for Emperor of the Earth, you have my vote. 

Thanks Again

You're welcome.

All my new music will not go into any kind of playlists, and I also cannot create any playlists with old music either. What is going on!!!

Do you have the side bar enabled? Press CTRL+S if not.

Do you have the menu bar enabled? Press CTRL+M if not.

Does File > New > Playlist work for you?

Can you drag songs from Music or another playlist on to an existing playlist?

Note you cannot add or remove songs from smart playlists except by changing their rules.

I've tried to copy and paste my last saved library to the itunes folder, but it comes back with that itunes library.itl error. Why is this happening and why did this start out of the blue? I removed all itunes software in the order stated  to correct the Windows Error 1114 and reinstalled itunes and now I can't get it to open because of the itunes library.itl error. I'm so sick of itunes right now I could SPIT! What the heck is going on with this?

Try again with a copy of your next most recent .itl backup. If that shows as corrupt too then it may be worth revisiting the steps you're using, or reinstalling iTunes again: Troubleshooting issues with iTunes for Windows updates.

Hi, I am not sure if this problem fits here, but it seems like a helpful thread for others.

I updated my Ipod software today and in the process it lookslike I corrupted my Library file. I know the process of grabbing a revious version and replacing the current one in the My Music folder, but whe I try to rename/delete/move the current library file to replce it, I get an error message "File is write protected, disk is full or file is in use by another program". None of these are true, I have even uninstalled itunes and tried to delete it, and I get the same message.

Any hel would be appreciated.

-D!

It should go without saying that iTunes needs to be closed when manipulating the library files. The utility Unlocker may be able to reveal which processes are preventing you from deleting the file and either close the locking handle or force delete the file. See also Empty/corrupt iTunes library after upgrade/crash for my most recent advice on pulling back an older library file.
