I can't help you with that (I don't actually use MS Windows here).

One really obvious thing to try, is to connect over serial again (hyperterminal or whatever), and hit "Control^C" to kill/stop the player process. This will give a command prompt.

At the command prompt, start the player again, but with the command-line option to "reinitialize" stuff. This is the standard way of recovering from a "stuck player", which is sort of how yours is behaving.

It will wipe out equalizer settings and various presets, but generally works.

I forget the exact command -- but others here will know it and post it for you. It's also somewhere inside the vast FAQ.
