An unknown error occurred (11111). Anyone have a clue what this means?!

Just now discovered that half the songs from a 100% MATCHED album are recieving this error, we all thought this was a problem with uploaded tracks.

I've given iTunes Match well over 3 strikes for this, I've probably given it about 15 strikes. I dont know why I'm still using it.

As stated earlier I encounter this issue solely with MATCHED songs. With uploaded songs I have no problems. So it is definitely not possible to pinpoint it to uploaded tracks. I am still in discussion with iTunes Support. Maybe something will get out of this.

Apple should have a BIG stoplight. With this problem no one should be using Itunes Match right now. Just have a web page that has a stoplight of green, yellow, or red. Oh and I did try a restore and it said it was corrupt. This is why I too keep multiple copies of my music in multiple places, two at different cloud sites. Yes, it is ridiculous but this is why...

I am having the exact same issue I have about 9 songs total out of a little over 1K. Apple email support says its something that they are working on but hasn't given me anymore information than that.

Has anyone else received a similar or more detailed explanation than that?

I have received a somewhat similar response from Apple Support. They have asked for my patience already 3 times with a senior advisor already in charge....

I also just started having this 11111 error on one of my matched albums. I hope this gets fixed quickly.

Edit: I waited like 10 minutes and tried again and the song downloaded. That was quick.

A common suggestion is to reupload the files. How do I get the files from itunes match when that is the only place they are. I uploaded them so I would not need to keep them on my hard drive or iphone. I could stream / download when I want. Now I have only 9 tracks of a 19 track album? How do I get the other 10 tracks?

Same for me...the most annoying thing is the Interruption while downloading the Library. I will get a new Mac soon and i definitly don't wanna sit and controll the progress. Hope there will be a Solution soon.

Well it seem the one track that did finally redownload for me was an outlier. I've since found another 4 tracks that either give me an 11111 error or an 5002 error. Both say that the file isn't available to download.

I almost feel like the files these songs were matched to were removed/replaced by the record studio or something. I can't think of another reason why Apple would lose track of the song the file is matched to.

I need to go through and check all my other files, but I have 29,785 songs in my iTunes Match library so this might take a while. I really hope that this can be fixed with a future version of iTunes or iOS 6, though I really really don't want to wait until the fall for this to be resolved, if at all.

The tracks that fail to download are all MATCHED tracks. To Macs and PCs I can restore the original file - or rip the CD again - but this creates duplicate entries to the library, and I cannot do this on iOS devices which having been swtiched to Match seem only to rely on iCloud files (hence I can no longer play the problem tracks on my iPhone.

This applies to most tracks on a few albums, which indicates to me that some content is missing or corrupted from Apple's master library of tracks; although in my case they all seem to be tracks which are listed as available to purchase on the Apple iTunes Store (so Apple DOES have the track files). The fact that it seems to be related to specific albums means you can make it less annoying having to babysit a download by sorting the tracks by Album before selecting "download". Then you will get a small number of several errors in sequence rather than lost of individual errors.

I have noticed today that many of the problem tracks can now be downloaded, so Apple does seem to be working to resolve the problem. There remain a few problems however.

Note I have downloaded the latest iTunes upgrade (10.6.1.7) which may or may not have helped.

Still in the process of downloading my full library. This has taken days due to the stops when the error is encountered. I have 6k+ matched songs, and several hundered random ones cannot be downloaded.

I identified a song that would not download or stream that a friend also has in itunes match. I asked her to try to download it and it worked. Same song, same CD source, different itunes match accounts.

I decided to call Apple support. After 45 minutes, I got a senior itunes advisor. He said they are aware of the problem, they are working on it, and it should resolve itself without needing to re-match the problematic songs.

I tried calling Apple too, I spent an hour on the phone, with 45 minutes of it trying to get them to understand what the problem was. After them trying to fix several items that weren't the problem they finally understood but were unable to offer any advice on how to solve it.

I have managed to solve the issue with all my music but it involved disabling and renabling match and letting it review my entire collection again and then removing the songs that were problematic and readding them from my timemachine backup. I had about 200 songs to do manually this way out of a 21,000 song collection.

I finally got my entire library re-downloaded, except for the problem files. I also figured out I can make a smart playlist of items not on this computer to isolate the problems. For some reason, the sort by 'icloud download' does not sort in order for me.

My music library is 6588 items. My ''icloud errors' (music not on this computer) playlist is 94 items. These are the ones that are not downloadable and cannot be streamed or played.

The problem items include matched, uploaded, and purchased. Most of the problems seem to be in groups by artisl/album, but some of the tracks on that album usually work. A few are random single items from an album (my library is 99% complete albums, if that matters; very few singles.)

Except for the 2 purchased items, I could easily fix most of these (I think) by re-matching or re-uploading. But I think I'm going to wait and monitor my 'iCloud errors' playlist to see if or when they become playable/downloadable.

OK, I couldn't leave well enough alone. I wanted to get a few artists back to working.

I think this was mentioned earlier, but the process to fix the broken files for me was:

1. drag the source files into itunes. There will be duplicates.

2. Add the new songs to icloud. Duplicates will disappear.

3. Delete songs from computer and icloud.

4. Download songs.

Something has obviously changed in the itunes copy of these songs since my original match. When I re-add the problem files, they are uploaded, not matched. Maybe Itunes does not know how to deal with previously matched songs when their source file is changed and different.

Can a 'Matched AAC audio file' be uploaded of you downloaded it before it was removed or changed on the store ?
