i have the a7 and have the same problem...the way i get it to run is go to the project manager, click on customize and choose weaponfx(00) then click the customize bar...scroll all the way to the bottom and change adv explosions to false..i'm not sure what the problem is but i am just a beginner and this is my first post in this forum..this does work but you might not have explosions but i'm not sure but it will at least run your game while you wait for a better answer...
