The slider revolution page says – “VERSION 4.1.4 OR OLDER MUST BE UPDATED IMMEDIATELY TO AVOID CRITICAL VULNERABILITY”. The version we ship with the theme is much more recent than that(4.6.4). You can take a look at the folder – “Revolution-slider-instructions” which has the updated revolution slider zip and documentation. If you still need help, pls send us an email via our profile page – http://themeforest.net/user/LiveMesh#contact and we will glad to help. Thanks.
