[Plugin: Google XML Sitemaps] 4 weeks failed Google Webmaster download

Hi,

continiously get the following error in Google webmaster tools

Error: The last attempt at downloading the Sitemap failed. The details below are representative of the last successful download

I have rebuilt the sitemap manually, it show fine at :

http://www.dangerousgoodstransport.com/sitemap.xml

and then re-submitted it on webmaster tools – still fails

I use the plugin on other blogs and have not had this ongoing issue with the sitemap.

Any ideas please?
