The sitemap generated just fine when I tried it. I've attached the results.
This is what I did:
Open up surveyor by going to this menu Insert->WebAssist->Surveyor->XML Site Map.
Use the default selected Create from site option and click next.
Enter www.logomatcentral.com/ in the Web Address.
The Sitemap is stored in a site that is saved to a local hd.
Changed the maximum pages to 1000 from 100 and hit finish.
