Itunes Library File Cannot Be Saved Mac

i keep on getting an error for itunes
the itunes library file cannot be saved.An unknown error occurred (-48)
i tried changing folder and file permissions but that didn't work. And my computer has been starting up really slowly since this started, and has been sluggish.(Also i cannot get to apple.com, nor the itunes store, i wonder if it has something to do with genius. in fact ill turn it off see if that helps)
also i am using itunes 9.0.1 on a 2 ghz aluminum macbook, and i recently upgraded my HDD, but it was working before the problem started.
any help would be greatly appreciated
