Borderlands » Action! and Borderlands 2

Hi,

I found an issue with Action! and Borderlands 2 (legit steam version)
The Borderlands 2 launcher shows up for less than 1sec then crashes when Action! is running. Everything works well without Action!
The game itself works, but hang just when I launch Action! when the game is still running.
This problem with Action and Borderlands only happen when the SMAA injector is enabled.
I tried with an non-legit version (without steam), the game works very well with both Action and SMAA.
Could you add support of SMAA injector with Steam please ?

Any help will be apprecited.

I didn't find the right solution from the Internet.
