iTunes error 4010. How do I fix this?

Hi

Hold option key whilst turning off match. Close iTunes, reopen, turn on match and select add this computer. Allow match to complete scan.

I have a Dell and run windows 8.1. I have tried the (shift button turn off), It didn't fix the problem. I also tried turning off music match on my devices, that didn't fix it. Oh and I tried uninstalling iTunes and re installing. I don't know what else to try.

Ever since updating to iTunes 12.1 the other day, iTunes match has not worked for me on my iMac. I have tried turning off using both the Option and shift keys and turning on without success.

I have also confirmed that iTunes Match is working on my Mac Mini running iTunes 12.0.1.26.

I worked on this for quite a while. This finally worked. I'm using a Dell running Windows 7 64bit.

1.) Do at your own risk of losing everything.

2.) Backup iTunes, you'll have to look elsewhere if you don't know how.

3.) I also suggest a backup of your music.

4.) With iTunes running, sign out of iTunes.

5.) Turn Genius Off.

6.) Close iTunes.

7.) Go find your iTunes home directory and change filename extension from 'iTunes Library.itl' to 'iTunes Library.itl_match_not_working'.

8.) Open iTunes, sign in, start genius, and then match should start successfully. If not, go figure out how to delete iTunes Match cache and reattempt (shift + turn off Match).

9.) Click Add File to Library... and go find and select the xml from your backup in step 2. This should restore your library. If not,changing the filename from step 7 back to iTunes Library.itl should get everything back to the way it was, albeit with broken Match.

10.) Savor all the riches of iTunes Match.
