This plugin uses AJAX & Thickbox to Display Dialog based Content Warning to Users. This act as Landing page to show message.
Unfortunately, I can't do much. You will have t make sure that Flash have the following Param to make it Transparent. otherwise Flash will overlap Thickbox!
<param name="wmode" value="transparent"> to your object tag
wmode="transparent" in the embed tag
You will have to open the CSS file and Edit to change Colours, Sizes and Styles. Open
