minor trouble with limewirelinux

I have limewirelinux installed. At the beginning it started right away & I got to 16,000 bytes of a file. Then it just shut down(In fact that is one of my questions how do I keep lime working without it shutting down , internet connection, program?, onetime I closed everything else & it close down.) when I restarted it did't download so I unistalled it & reinstalled it. Same thing was happening it started at first. It also worked at a different time but it would not open many files.(eventualy I had 12 files without one being downloaded. Why?) So my question is why does it take 30 mins to start one download(is it me, or the options.). I have used winmx & kazza it's not the same! Next keeping the limewire open while I'm hacking. Thanks to you!
