Have had this problem but never had this problem before 1.68. Played great on 1.66 and then 1.68 came out and haven't been able to play Arma since. Just redownloaded it today, again, clean installation, verify the files, no mods - unsubscribed from all of them, and nothing. Game freezes on main screen.. nothing nothing nothing and no one at BI seems to know what is the problem.............. I have been on twitter like crazy trying to get help, the feedback tracker does not work for me or just does not like me... I wish I knew what was wrong with the damn game. Had Raptr on computer from when I got it... but changed AMD for GeForce 1060 when we first got computers... and that didn't do anything either. Our firewall, microsoft, only upon first installation, do you have to allow the firewall to recognize the game, computers are directly wired into the router... .....    I have idea what else the problem could be. Changed from 64 to 32 and back.. same thing, freezes and nothing.    Specs..    AMD A4-7300 3.80GHz 8 GB DDR3 GeForce 1050  (Came with AMD Radeon HD 8470D Graphics... sucked whatever, changed that before we really started using them,... 2nd day bought the GeForce cards) 1TB with Windows 10 64bit   Had these specs when the 1.66 update and game was beautiful.. ran no problems whatsoever.. no lag or nothing... 1.68 happened and boom.. nothing, like I said..    What on earth is the problem????????? I want to play again!!!!!   Thank you very much if anyone can help me out, I would greatly appreciate it.
