 - Certainly, we’re experiencing a recall on some models. Which one do you have?

 - I have the N.5250.

 - OK, tell me about the problem you’re having.

 - Well, at first, the sound quality started getting worse. Then, it completely froze. I tried restarting it but that didn’t work.

 - Sounds like a problem caused by AAC* files. Don’t worry; we have a driver to fix that.

 - Great! How do I get it?

 - Just download it from our website and upload it to your player.
