Links not working in IE

Have you tried deactivating your plugins and switching to the twentytwelve theme to try to identify the problem?

Beyond that, unfortunately, that’s really a horrible theme you are using – that vendor is known for doing sleezy things like embedding encrypted links that can do bad things to your site. They also don’t comply with the GPL licensing requirements of WP.

I’d really suggest you read this article and find a new theme ASAP.
