there is a new patch available
right click on Arkham Knight game in steam
and go to Properties, Under Betas tab, select Patch2 in the dropdown and press okay.
Update: nevermind, the patch has been removed from the public

dont do this if you want the trainer to work.. our trainers are mostly for legit releases, not beta patches
