Problem creating my sitemap....no sitemap created.....help!!!!

[rags]

I previously created a site map without problem from this site.  I just now redesigned my site and I came back to get an updated site map.  I run the free online sitemap generator and it doesn't index anything.  It doesn't create the sitemap...it runs but then quickly comes back and says pages indexed 0 and there is nothing in the box below where the code is.   Help !!!!!  THanks.
