New Install, Can't Fire

Greetings all, I'm returning after a very long time. I've installed the new crossfire 2.0 client and went to start the single player campaign and I can't fire despite confirming that mouse 2 was selected as my fire button. Does anyone have any clue why this is happening?

They were selected, it just wouldn't respond for some reason. I ended up reloading or docking and undocking from a station and it would correct itself. Not sure why it would do that but there's a solution.
