Activacion slider revolution

Hi,

When you purchased our theme on Themeforest, you do not need to add any license keys, you still get the latest features of theme. These keys are to let you update those plugins automatically. If you want, you can buy those plugins for your own. Otherwise, you can dismiss these messages.
If there is any updating, we will update on theme, and you can wait for the latest version then update for your site.

So, we cannot give you the key to activate plugin revolution because it was applied for demo site already. If I am misunderstanding you mean, pls provide me your admin account, take the screenshot then I willc heck for you

Regards,
Yame
