I get unknown error (-54) all the time when trying to update Match or Genious

I also created an empty library & Match had the identical error 54.

I then down loaded 2 albums from the store that I have purchased

Match continued to have the same issue, but Genius would update.

very confused...

Does this have something to do with a "locked file" within my iTunes Library that I read about in one of the threads?

If it does, then how do I fix this?

since Match still had the same error with No music & with only iTunes down loaded in my iTunes Library on my PowerBook, I do not see how it is a locked file issue only. Since Genius did work without my full library, I may have some locked files. Still confused...

When trying to update Genius & iTunes Match, I always get this error the same time as iTunes has gathered all the info & has just started sending it to iTunes:

"We could not complete your iTunes Store request.

An unknown error occured (-54)

There was an error in the iTunes Store. Please try again later"

I always get this error no matter when I try.

I went to the Apple Store & they could not help me even with an appointment 😟

Their guess is that it has something to do with the SW on this Apple Macbook Pro Retina notebook.

We tried creating a different iTunes account on this notebook & that received the identical error.

I did try Genius & Match from a different Mac notebook, but without my library & there is no error.

This notebook has worked for ~1 hour since I got it new about a week ago & I've had this notebook for 2 weeks now.

Genius & Match both work on my PC notebook, but for some reason my iPhone or my iPad will not sync. I always get Time Outs and the Sync never completes -> message that the Sync is finishing forever or until I unplug my USB cable.

Does anyone have any suggestions?

Thank You,

I've also reloaded iTunes onto my Mac notebook. I cannot think of anything else to try 😟

I get this message from iTunes for both updating Genius & iTunes Match = any clue would be greatly appreciated:

We could not complete your iTunes Store Request. An unkown error occurred (-54)

There was an error in the iTunes Store. Please try again later.

Thank You,

Thank You!!!!!

I can finally use iTunes on my MacBook Pro Retina 😁
