how do I fix error 4007?

Hi, I have the same error message when I try to 'Match' when using my library.

I managed to 'workaround' it by 'matching' when logged in to the store instead of my library.

weird but true - hope it works for you

Sign out of itunes and sign in again. iMatch must be reauthorized with the computer, but it doesn't take decades to finish the process.
