Blank page after installation?

I was really looking forward to installing it. I have two other sites and the plugin works great. Then today I tried to install it and the moment I click to activate it, the main page goes blank (white page). I deactivate and everything comes back. Then I activate again and I get the blank page. Really weird.
The only difference with this site is that I am using Slider Revolution, but not sure that has anything to do. Got a ton of other plugins installed but on the other servers also.
Scratching my head a little. If anyone has an idea I am all ears :-)…..
