[Plugin: Google XML Sitemaps] Wrong result in Google; wrong path

I’m using Google XML sitemaps. Activated it and added it in the Google webmaster tools.

When I search my website on google it finds my website http://www.kcmusic.nl/wordpress/page, but that page is not found, because I made a redirection to http://www.kcmusic.nl/page. (see http://codex.ww.wp.xz.cn/Giving_WordPress_Its_Own_Directory).

The search URL is: http://www.google.nl/search?hl=nl&q=kc+music+kelly+veerman , the result at the top is my website.

Help!?
