Problem with search results

[Nexxus]

A few weeks ago, all my LimeWire settings for some reason reset themselves, including all the terms and such that I had listed to be filtered out. Now, when I try to do searches for songs/videos, I'll get results, but then some results will disappear. They're nothing that I have listed in my filters, they just disappear. I'll have, say, 50 results. It'll look something like this (50/250) but that keeps changing. The 50 will sometimes increase, sometimes decrease. I'll lose valid results. And why does it keep coming up as this fraction now?
