Thx Ben
Download your Experience add-on. We may need to take a look at your theme to see if it is overriding the plugin style css rules.
Did You know that as a Premier subscriber you can post in the Premier forums?
if after enabling the Experience add-on that allows you to add some css rules , or if you do not see the Plugin Style you need under the Settings/view the developer may be able to add a plugin style that works with your theme.
