Hello,

as discussed in http://www.xml-sitemaps.com/forum/index.php/topic,911.html:

this issue has been addressed, thank you for your feedback and sorry for delay.

Please re-download sitemap generator package (using the same download link) and reinstall it.
Ok, now it works, except documentation.html... Could you check?
