Same problem here for me . The models in fs trafic are the best but now i cant use without the trafic control disabled so therefore wont work with beyond atc. I Tried to rename the folder like the above post says but while the batc app did run i didnt get any trafic in the sin. I sent a ticket to just flight . Hope they can sort it because so many people use there trafic for batc in the same way as i do
