iTunes error -54/-57 after updating to Version10.6.3
Hi,
I hit Software Update on my MacBook a few hours ago, and among the updates was one for iTunes, updating it to V 10.6.3. So I hit "Update", and thought nothing of it.
In my iTunes, I had about 30 or so app updates to download, so, I figured, since I had some time, to download them in the background while getting on with work. Done it many times before, as i'm sure most of you have. However, every few seconds, I get bothered with the iTunes logo poppping up in the Dock, and an error message reading "The iTunes Library File Cannot Be Saved. An Unknown Error Occoured", and then in brackets either (-54) or (-57).
Does anybody have any idea what this is, and how to fix it? Besides hitting the "Do not disturb me again" button. I'm guessing it's a bug in the new version, wondering if anybody else had this problem?
MacBook Pro (13-inch Early 2011), Mac OS X (10.7.4)
