Limewire 1.6d does not work on my computer as well. (sniff sniffal )

I tryed Christophers experiment but alas still does not work. So I tryed this...

I went to options/network/listening port and tryed to change value to 6346, I got the following mesage
"Port not availabal. Please select a different port."
I get the same mesage for every different # I type in.

Could you please look in to this chris... thanx

P.S. connections tab shows nothing, running wi***b, WL 1.4 worked fine, tryed to reboot ect...
