Well, I've had the same problem as many of you. I upgraded my iPhone 4 to iOS 6 and then **POOF** all my music was gone and iTunes Match did not work. 😟 I tried switching settings on and off, restarting the iphone, etc. to no avail! Then I came across this thread. I tried iExplorer. I actually had an older version which didn't open with Mountain Lion, so I followed the link above and donwloaded the new version from the site and replaced the older version with it. For me, it DID NOT work. I told it to delete the iTunes_Control folder but the process took forever and it never actually deleted. Strange. I had to force quit the app a number of times as I tried this.
So, then I tried "DiskAid" which is an app that can accomplish the same task of deleting the folder. I used this app and right away it deleted the folder. Yea! Then I rebooted the phone, etc. But, it did not fix the "no music, no iTunes Match" problem.
So, I thought. I am an American with an American iTunes account (iTunes Match), but I live in Japan. Hmmmm. I turned off my cellphone network in settings so I only had WiFi to work with on my iPhone and then started the music app. **BAM** It worked!!! 😎
I have used iTunes Match from day one and always in Japan, even though Japanese account users can't access iTunes Match, I could. Anyway, my music is currently downloading fine. I have now just turned the cell network settings back on and music seems to continue to download fine. The question is, will it continue to be fine or has Apple changed something to hinder my expatriate life. 😝
Maybe this will help others living abroad. Happy iPhone-ing.
