Hi

I can't start up Far Cry 4 on my laptop.

It runs Far Cry 3 fine

I have the following PC specs
Processor Intel(R) Core(TM) i7-3630QM CPU @ 2.40GHz

Video Card 1 NVIDIA GeForce GT 650M
Dedicated Memory 2.0 GB
SLI

Memory 8.1 GB DDR3


I can't even start the game up.
The play button goes gray and then after a few seconds white again.

I have updates drivers and unpluged all USB devices, and diabled SLI.
Any other ideas?
