My PC won'[t recognize my Yamaha TSR-7850, help!

Yamaha said 9xxxx was probably an error message. I can't restart it now, or get it to work. Unless someone has an idea I'll probably try to return it.

I had it hooked up how you say, but now it's frozen.

That certainly isn't encouraging that Yamaha isn't sure....
