Domain Error in Save to iTunes f(x)

I've updated your app, it's running fine, however, on certain files I receive an Error message:
Error
Domain=NSCocoa...

I just had it occur for the first time today.

Also, I'm still unable to transfer files into photo album, however, that's not my main concern at this time.

Pls use mola_diver@me.com for correspondence.

Thx for any input; still love the app, $3600 saved so far!!!
