Please helpppp!!!

When I first used the Sitemap Generator it worked perfectly, however, my site of 24 pages came up with 10 errors…most of them being detected due to my favicon code, one being from a URL that had ‘&’ that in it that was linked in many of the pages and then a deleted sitemap page was detected. Like the video demonstrated, I deleted all of these failed pages, then had the bright idea to close out with exporting the file and restrat the generator and this time include my favicon in the "filter" are so it wouldnt interfere. However, now when I try to generate a new sitemap it only shows one page, my home page as for the total amount of pages on my site and thats whether or not I include the favicon file in the filter or not. I think the ‘&’ url was something important. Can you please help, does this sound familiar. I am building my site on office live, if that helps. Thanks for your attention to this and thanks for this great tool!
