Could you please specify where that folder widgets is supposed to be? because I can not find it. THere is also no admin root. Just wp-admin, but there is no widgets folder in there. There is a widgets.php in there but no widget-tweet.php.
OK, but where is that green.css or the skin folder? I installed your theme using that wordpress install option. Is there an option to just replace the .css or do I need to make a complete fresh install?
