This theme (and the plugins that were included with the theme) haven't been updated in almost two years. If the author is no longer going to support the theme, they should provide a replacement theme at no additional cost.
I purchase this theme an most of all the plugins that make it work is out of date and it's no longer supported. For me to update the plugins I need new license which they will cost more than the theme itself:-(((((
When installing the theme's demo content, the slider wasn't installed. I found the slider contents in a separate zip folder, and installed them - but the slider still didn't behave anywhere near the way it did on the site. I've been waiting for 3 days from a response from the author - and nothing.
