Every time I start DCS, I get an error message saying 'Steam Authorization Failed' followed by a list of every single module DCS has to offer and the message 'The following DLCs are not authorized and will be disabled'. After pressing OK, the window closes and DCS starts but all I get is a black screen, it is still running and I can get the Steam overlay over it but nothing will change for hours after that. I will attach screenshots to aid with comprehension. I'm sorry if this is not the right place to post, I can't find anywhere else which fits the problem.
