Ya might wanna ignore PYMUSi on this one.

I'm not tech savvy enuff to explain all you need, but you can find the port setting thru Tools>Options>Advanced>Port. In my Windoze version, the default is set at 6346.

If that ain't the problem, you can try updating your modems/ethernet cards software, or hope some one who KNOWS this stuff reads your post.

Good Luck.
