MacPhex doesn't find anything

I installed MacPhex 0.7.3 and MacPhex Update. I designated an upload (shared) folder and a download folder. I tried a search and all that happens is that "it" says "still searching". As much as I hate to read, are there instructions somewhere? Not only do I not get search results, I don't have the foggiest idea what the Guntella Net and Monitor Search pages are for. I use Limewire with great success, but maybe Phex has some other nice features. Can someone help??
