LayerSlider & Revolution Slider problem with a fresh install of Boldial

Hi,

I just installed Boldia, but when I tried to activate Revolution Slider, I get this error (“couldn’t activate, for a fatal error occured”), although I copied/pasted the entire folder :

Warning: require_once(/home/mydomain/www/wp-content/plugins/revslider/includes/framework/include-framework.php): failed to open stream: No such file or directory in /home/mydomain/www/wp-content/plugins/revslider/revslider.php on line 59

Fatal error: require_once(): Failed opening required ‘/home/mydomain/www/wp-content/plugins/revslider/includes/framework/include-framework.php’ (include_path=’.:/usr/share/php:/usr/share/pear’) in /home/mydomain/www/wp-content/plugins/revslider/revslider.php on line 59

Could you help me understand what is going on, please ?

Also, I get this caveat for LayerSlider :

You need to activate this site in order to get upgrades or premium support for this plugin. Purchase a license or enter an existing purchase code.

How can I activate my site and get upgrades or premium support for this plugin ?

Best regards,
