I have issues with DarkMultiplayer - it is shown as incompatible mod after game menu loads. And I can't click on Accept on the DMP popup.
My installation procedure:
I downgraded my KSP version to 1.3.0
DMP client installed (downloaded from the website)
DMP update downloaded - I ran it just to verify the installation and version - no update found
I tried to run the game in x86 and x64 mode
Still no luck.. any ideas?
