Re: First time launching and can't click "OK" on initial splash screen
Ive had this issue intermittently since BF1 launched. Not been able to find a complete cure and I think it happens for a variety of reasons, but I do have a simple solution that works for me every time.
Go into BF1 in my docs/settings and delete all files in the settings folders (they are on the cloud anyway). then relaunch and BF1 should launch in windowed and fully clickable. Once the profile updates in will revert to fullscreen, so if it happens again and you cant click, just repeat and then be sure to go into settings and set it to windowed mode once launched.
Its not ideal as you can only play in max 1080 but at least you CAN play. Hopefully EA or DICE will fix this once and for all very soon as it really pissing a lot of people off!
