Hey fellas,
I opened a support ticket with BI. I recieved this reply.
"Hello, please go to your Documents, right click Arma 3 folder, select "Properties" and make sure that it is not set as "read-only". Do the same with the files inside the Arma 3 folder. This should fix the issue. Thank you. Best regards, Dominik Flandera Bohemia Interactive"
I tried this but the "read-only" box keeps rechecking itself for some reason. Try it and see if it works for you or not. I sent him another email. I'll let y"all know what he says.
