Ok apparently I need to shoot the seeing eye dog because neither of us could find this problem or figure it out even after reading all 35 pages of this thread. Everything installed right (the third time anyway) and it SEEMS that everything worked right right up until I go to create the sitemap and I get this error:

It appears that everything but the sitemapindex file created correctly, just to make sure I opened it up and this is all it had in there:

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="gss.xsl"?>
<sitemapindex xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9
http://www.sitemaps.org/schemas/site.../siteindex.xsd"
xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
</sitemapindex>

The other three files have what appears to be the correct info in them so it has to be just a little glitch somewhere.

I am using GoogleSitemap ver 1.3.9 and ZC ver 1.3.7
