I added the command line in Origin without quotes.

"-RenderDevice.AmdCrossfireEnable 1"

I selected the profile in AMD Crimson. Crossfire is turned on, Crossfire logo turned on. I have purchased the game (Not the trial)(tried both .exe files). Using MSI afterburner only 1 GPU is active.

All other crossfire games are working great.
