Hello' Good day! Just gonna ask if you're now requiring a legit copy of Battlefield 3? Cause I just came back to play the server again but it requires now an Origin Application? How can I fix this, should I buy a legit copy of bf3/bf4? cause wayback 2016 I have played the servers without a legit copy of bf3 and bf4, how I can't play the server now? Hope anyone can reply, TIA
