Hello, try deleting all files in C:\Users\*user name*\Documents\Arma 3\

Deleting *profile name*.Arma3Profile, *profile name*.vars.Arma3Profile and Arma3.cfg should be enough.

Note: Deleting those files will delete all your settings and game progress, also deleting the folders will delete any and all custom missions you made in SP and MP editor and saved them, as well as all saved progress in any mission you played.

I strongly recommend to backup those folders.

Thanks Raedek, But as I have stated, I have already tried to manually delete folders ect. but nothing seemed to work, I will try it again, BUT ALL OF MY GAME DATA! COME ON!

Please try verifying game integrity in steam. RMB Arma 3 in your steam library, click properties, select LOCAL FILES tab then select "VERIFY INTEGRITY OF GAME CACHE..." If there are any corrupted data this should fix them.

After steam is finished with any download that may start after verifying launch Arma without any mods.

Tried that too
