Revolution Slider Error: Slider with alias home-slider not found.

Hi,

I have tried to customize my sites and afterwhich I wanted to reset the theme to the demo and try again.

However, when I re install the theme, they say the installation failed. Whereas reimporting the demo doesn’t give me back the original template but showed the message below:

Revolution Slider Error: Slider with alias home-slider not found.
Maybe you mean: ‘splash_slider’ or ‘splash_slider1’ or ‘splash_slider2’ or ‘about-slider’ or ‘about-slider1’ or ‘about-slider2’

Please help.

Thanks!

Regards,
Janice
