hmmmm . which version of Limewire are you using eg 4.9.30 or 4.8.1 or something in between. and is it Windows or Mac?

What do you see if you go to options> sharing?

Options> directories for sharing is not on my version! but if you have that then that is where you should be entering your shared folders.

Also I do not have options debug. I have Bug reports, which means, in its default state, that bug reports get sent automatically to limewire if anything is not working just right. It is usually wise to leave that section well alone, as changing the settings will not improve anything!

Im a little confused as you mention features that are not quite the same as the features I am familiar with. No doubt someone will know exactly your setup
