I'm getting an error message in ITunes -42408 ?

I know this is an old post, but I found a solution in another support post (credit to andjoa), it worked for me!

Hi

I know this thread is a little old but I thought I would leave the solution I found that worked for me. I'm on a mac mountain lion.

I tried uninstalling reinstalling and that didn't work.

You may want to back these folders up before trying this.

1) Quit iTunes.

2) Go to System/Library/PrivateFrameworks/

3) COPY the following folders to a different location just in case

AirTrafficHost.framework
CoreFP.framework
DeviceLink.framework
iTunesAccess.framework
MobileDevice.framework

4) Delete them from the original location.

5) reinstall iTunes

6) Smile no more error -42408
