Q: iTunes error 13014

Try downloading and reinstalling iTunes from here -> http://www.apple.com/itunes/download/

Do you have an iPhone, iPod touch, or iPad connected to your computer when you see this problem? And does it go away if it's disconnected?

If it only happens when a Apple device is connected, try the steps in this article or restore the device.

One thing that may be the problem is were your files are located

I have my entire library stored on an external hardrive and that somtimes causes problems for me

so the location of your music witch you can find and direct in the preferences and then under "advanced"

in this spot you can change the location of your library this may be the issue.

I am not conferming that this is the issue nore the solution for the specified error.

I will contact apple support and try resolving this issue and will fallow-up with the solution if there is one

This just happened to me today. Searched multiple threads and an archive from 2008 helped me. I did not have any iphones, etc trying to sync which also seems to generate the 13014 error for some folks, but I had a problem shutting my imac down i did have to force quit using the button on back of my imac.

My problem had something to do with Genius, so i deleted an itunes library file genius and itunes opened right up.

See the thread here ....https://discussions.apple.com/thread/1749728?threadID=1749728

I looked in the directory where my iTunes library is stored and found a file called iTunes Library Genius.itdb.lock. I'm guessing this file gets deleted when iTunes quits normally, but stuck around since I did a force quit. Anyway I just deleted that file and iTunes opened as normal.

...

In my case, the hard drive was full. I deleted something and restart itunes again and it worked.

I had same error, but it was solved as simply as re-starting my Mac.

Specifically, I had a disk crash on the external drive where I keep my iTunes folder. After recovering this from a backup, I had the 13014 error. However, a simple restart fixed everything.

This may be a unique fix, but this happened to me when I backed up my iTunes library to an external hard drive and attempted to put the files back on my computer's hard drive. I ended up filling my computer's hard drive due to duplicate files being transferred. I deleted a fair amount of those files and the error message disappeared immediately. It may be that your hard drive is simply too full and the system can't recognize it.

yup unplug your iphone/ipod or whatever and the error will go away

I had a similar issue.  Here is my approach that fixed the issue.  I have my files and my iTunesLib on a Drobo.  I turned off all network connected devices and disconnected my network connection.  I turned off my iMac and unplugged my Drobo.  I rebooted and opened up iTunes.  I created a new blank Library on the HDD.  I shut down iTunes.  I plugged in the Drobo, opended iTunes using Option to find the old iTunesLib, and all worked well. 

Same error here. My hard drive was full.

I believe I have the same issue, but I cannot access finder to delete any files? any suggestions?

^Same

Same for me, should have a clearer message

I had to delete "iTunes Library Genius.itdb-journal", but the same general idea.

All better! Thanks for the help!
