I didn't try to run it in the terminal. I just tried running it from the screen....my terminal doesn't recognize /usr/local/bin/gtk-gnutella as a directory...sorry if i sound really stupid about linux, it's just that i have very little knowledge about what i am doing...i'm just very confused about it.

I went into "my computer" and then switched the location to /usr/local/bin and the file is right there....when i tried putting /usr/local/bin/gtk-gnutella in, it gives me this message:

Nautilus has no installed viewer capable of displaying "/usr/local/bin/gtk-gnutella".

Help?
