error 4001 iTunes match

I have the exact same issue - only recently came up, was working fine a few months back. 4001.

This "solution" does not work for me:

Hold down the Option Key (⌥) and at the same time click ‘Turn Off iTunes Match’.

Click Store on the menu again, then click ‘Turn on iTunes Match’ (but don’t hold down anything this time, just click it).

Same Problem.

Error 4001 and 4010!!!

Hello I know how to fix this error. I had this same problem and I researched it extensively. I found the solution. Follow the directions on this link exactly. It will work. It is happening because your itunes is storing the cache from the previous session *which didnt work and so now it is just giving you the same message over and over again. SO that is why you need to hit shift on a PC options on a mac while turning off itunes match. this will cause the cache to reset and it will restart the process and it will match your songs. I hope it works. Let me know what happens please.
