Sitemap problem

i installed vbseo, i got sitemap_1.xml.gz at my "forums/vbseo_sitemap/data" folder. When i tried to add this file as sitemap in google, it gave an error something like "your sitemap must be in www.xxxxxforum.com/forums/ , because i added my site to google as www.xxxxxforum.com/forums/. This folder is my root folder. When i copy this file to root and add to google sitemaps, it only indexes my vbadvanced portal page, not forum page.

So ;
1- How can i add my sitemap_1.xml.gz in its original location to google
2- How can i index my forums page, not vbadvanced portal page.

Thanks

Thanks for your reply.

i did number 1 and 2, now google accepted my root folder, and i add this lines to my extraurl file ;

http://www.xxxxforum.com/forums/eindex.php (this is my main forum index)
http://www.xxxxforum.com/forums/archive/index.php (and archive page)

Google has verified my site, accepted my sitemap, but threads in my archive stiil don't appear at google search. only few threads in portal page are listing.

What is the problem ?

Thanks.
