Hi There,
Please your cache and test it again.
If that does not solve, there is a bug ha penning on a few installations that ThemePunch is working on.
In the meanwhile i recommend you downgrading your Rev Slider. To do that access your site via FTP and go to:
wp-content/plugins/ and substitute the folder revslider for the folder inside the zip file from the link below:

You can try to upgrade as soon as a new version is released.
Hope that helps
Joao
