orion7x, the suggestion to install theme check plugin was to identify any old code which need to be changed or upgraded if you really want to use that theme.
For example, when I used theme check for the Elements of SEO, it showed that the theme had no wp_footer hook which is required by many plugins including the new WP navigation bar, so you might want to manually add <?php wp_footer(); ?> in footer.php of your theme immediately before </body></html>
The results of the theme check on my end:
WARNING: Found wrong tag, remove widgets from your style.css header.
WARNING: Found wrong tag, remove valid XHTML from your style.css header.
WARNING: Found wrong tag, remove valid CSS from your style.css header.
