Got it drmike, the solution was really, really, really, simple.
You see, the "feed-rss2.php" file in the wp-includes directory beigns as:
<?php header('Content-type: text/xml; charset=' . get_option('blog_charset'), true); $more = 1; ?>
<?php echo '<?xml version="1.0" encoding="'.get_option('blog_charset').'"?'.'>'; ?>
<!-- generator="wordpress/<?php bloginfo_rss('version') ?>" -->
<rss version="2.0"
xmlns:content="http://purl.org/rss/1.0/modules/content/"
xmlns:wfw="http://wellformedweb.org/CommentAPI/"
xmlns:dc="http://purl.org/dc/elements/1.1/"
<?php do_action('rss2_ns'); ?>

I added a ">" at the end right after the do_actio('rss2_ns')....as this:
<?php header('Content-type: text/xml; charset=' . get_option('blog_charset'), true); $more = 1; ?>
<?php echo '<?xml version="1.0" encoding="'.get_option('blog_charset').'"?'.'>'; ?>
<!-- generator="wordpress/<?php bloginfo_rss('version') ?>" -->
<rss version="2.0"
xmlns:content="http://purl.org/rss/1.0/modules/content/"
xmlns:wfw="http://wellformedweb.org/CommentAPI/"
xmlns:dc="http://purl.org/dc/elements/1.1/"
<?php do_action('rss2_ns'); ?> >

And that solved it. My feeds now validate and I can now use feedburner for stats, and also have my feeds in any rss reader there is.
Thanks a lot drmike for being there with me in all this giving support. Sorry for all this too.
Now, I have to check the other files, RDF and ATOM, to finnish all the validations and also activate all the plugins, one by one, and see that everyting is ok.
Thank you again. Kind regards, :-)
