I had a strange experience (at least to me) when I upgraded my software.
1. Downloaded the new version and formatted on my memory stick
2. removed the bluetooth dongle and plugged in my memory stick
3. Started the machine, and the only thing that lite up was the phone, but it did nothing
4. The machine was clearly downloading the information as I could see lights flashing on my memory stick
5. I kept waiting for the machine to boot up or give me some sign that the machine upgraded the software, but nothing.
6. I waited until the stick stopped flashing (about 10 minutes), shut down the machine, removed the stick, and replaced the bluetooth dongle
7. I started up the machine, and it booted up with the newest version...seems to play normally...
