Please sign in again. iTunes Match has encountered an error.

Still failing at the upload step even after running as Administrator, logging out/back in and such.

Best hardware, yet forced to use the worst software...

Now after deleting the .plist file, it refuses to sync at all, even with the files that previously triggered the problem removed. FFFFUFUUUUUUUUUUU

I've finally fixed my own problem with this on my MBP, it turned out to be the cookie settings in Safari that were the problem.

I'd switched Safari's privacy settings to always block cookies as I don't use it. There must have already been an iTunes cookie in there before I made the switch, but at some point in the last few days it must have been cleared out and then I was getting the match problem and couldn't view my iTunes account details either.

Switching the cookie setting back to block: From third parties and advertisers, logged into iTunes acount again and then match worked finally.

THIS WORKED FOR ME! Nailed it! How weird. I don't even use safari as a main browser.

I have this problem on my work laptop, my home MBP, and my home Windows desktop. iTunes is updates. About every-other-time I open iTunes on any of these machines I'm asked to re-sign in. I keep hoping and praying that an iTunes update finally fixes this. If this isn't fixed by November, I'm not renewing iTunes match. I love the service but I can't be hassled with signing out, signing in, and re-adding my computer to iTunes Match.

You people saying some solution worked for you, could you please clarify which post specifically helped you? There are many many pages now...

Thanks.

This is what worked for people running Windows

1. Launch iTunes as an admin (right click on your iTunes icon and click "Run as administrator."
2. When iTunes loads, sign out, then sign back in.a) At this point, upon signing back in, my Match icon was gone from the Music folder, and it was looking for me to turn on Match again.
3. De-authorize the computer, then authorize again.
4. Now turn Match back on (the process seems like a quick check, and did not take as long as the first Match scan).
5. After iTunes Match is complete again, I was able to close iTunes open again with "Run as administrator," and my match was all good.
6. Close iTunes and reopen without "Run as administrator" and it's still good, updates Match with no issues.

Step 5 should not be necessary.

Ok, thanks! I just went through the steps and I didn't get the message on Step 6 so that is a good sign however my problem has been really intermittent. I'll load iTunes a couple times tomorrow; fingers crossed that this solves it for good.

But I do still have the exact same issue on my Mac....

Setting program compatability to "Windows 7" and then setting the itunes to always "Run As Administrator" for all users fixed the issure for me on Windows Server 2008 R2.

I know Match is still beta, but isn't apple going to fix this some time soon? I'm getting tired of turning match off and on all the time!!!! 😠

The public release of Match has never been beta, not sure where people keep getting that idea.

I have had the same problem repeatedly. Repeatedly means every time I start iTunes on my MacBook Pro with all the latest software installed.

Each time I turn off iTunes Match and turn it back on again, signing in again, and authorizing this computer again. And then it works until the next time.

I am looking at 5 pages of users who are having this problem and you know who is missing??? Apple Tech Support!

Are you turkeys in Apple Support hiding in the bushes? At least you could come to the surface to say, "We know this is a persistent bug and we have no idea what causes it or how to fix it."

Instead you are doing a great imitation of Microsoft Tech Support. Ignore it and hope the problem goes away. If you are trying to emulate Microsoft, you are doing a **** good job. Maybe we should all start emailing Mr. Tim Cook to get the attention of someone at Apple instead of wasting our time here.

It really doesn't matter if it is out of beta or not. Apple sells it as a service no matter what they are calling it.

I agree, this bug has been an issue since iTunes Match launced. It also is an issue on Mac OS X AND Windows. I've tried multiple things in this thread, and they all have been short term fixes for a bug that keep cropping up. Don't understand why Apple can get it right on iOS devices but not in iTunes...

This continues to happen on my Windows and Mac machines. I've followed the step-by-step instructions given here and they only seem to help for a week or so and then this message crops back up. Very frusterating. Other users report not having this issue. The fact that I'm having it across all my machines while others say they don't have any problem leads me to believe that the issue is actually on Apple's side with how they handle their accounts than on the iTunes side. Just a guess though.

I sure hope with the release of iTunes 11 this bug is squashed.
