music not synchronising on iPod Touch
I'm trying to sync music on iPod Touch with iTunes. For some reason iTunes gives me an error message "unbekannter Fehler ist aufgetreten (-50)" and:
- the music I bought via iPod is not playing anymore (it's there but the music cannot be started)
- the same occurs with music I downloaded from the web
can someone explain how this can be solved?
iPod touch, iOS 6.1.3
