I'm having the same 'black' screen problem with defera...
have had it for about 3 months now...

I can see the headers and name tags, but no ships, nothing just empty black, not even my ship appears. my HUD is still active and I can see movement from other ships, because their name tags are moving around. I reported the bug in-game about a week ago with no response yet... but didnt think it would be any time soon...

running a full up to date system with intel HD graphics, and all updates are current...
