Q: iTunes problem downloading, an unknown error occurred (-54).
I am getting unknown error occurred (-54) message from iTunes and can't seem to get ride of it. I have tried deleting it in downloads, but the next time I check for available downloads... there it is again.

From an OS9 reference, error -54 is a software lock on a file or a permissions error. (Although there is no formal list of OSX error code some of the old codes still apply to OSX .)
First, try simply restarting your computer.
Try quitting iTunes, then deleting the .xml (not .itl !) version of the library file in the iTunes folder (iTunes will generate a new one).

Error -54 possibly related to Touch Copy - https://discussions.apple.com/thread/3727114 - cleared by deleting preferences on iPad.
