Activating Slider Revolution

I just install BeTheme and try to activate SliderRevolution plugin but it failed. I tried to uninstall it and upload the revslider.zip inside the package but in both case I had this error:
Plugin could not be activated because it triggered a fatal error.

Fatal error: Uncaught exception 'Exception' with message 'No
captions.css found! This installation is incorrect, please make sure to
reupload the Slider Revolution plugin and try again!' in
