@dessy.raza: Sorry, but you’re using a premium/paid theme. It’s best to go to the support site where you bought the theme – http://themeforest.net/ – for help with customizations and issues. You paid for support when you bought the theme, so you should contact the people who sold you the theme.

These forums are for free themes available in the WordPress theme directory at http://ww.wp.xz.cn/themes/. See http://codex.ww.wp.xz.cn/Forum_Welcome#Commercial_Products

use negative value at margin top property now you have it 0 px ;

.logo {
margin-top: -10px;
}

It may be a problem with your theme,if you bought the theme please follow the advice of @songdogtech and contact them, if you use it from torrent files … be careful because often they put backdoor in code.
