I got error message 4001 when trying to upload music to imatch

2 years later and still getting the same error, wth APPLE?

iTunes 11.0.5. on a new iMac, just purchased. So why hasn't this problem been addressed?

nope, didn't work.

Sorry that was the 1st thing I tried, no luck.

Yup! Sounds like something they would do, complete idiots!

I just followed whatheck's instructions and it worked!

Thank you!

On another topic, why can't I change the order of my songs in my playlists?

Everything is grayed out, including the columns.

Amazingly, 3 and a half years later, this trick worked for me. Thanks so much!

I had this problem when I was using wifi that was extended over a "powerline" type network. As soon as I switch to the wifi directly from the router it worked fine. I use different SSID's for the router and extension (which happens to be an airport express).
