Demo questions/problems

[Q]

After some technical problems due to my older computers I finally installed the demo and started a game on "easy" level. I even realized after some crashes that there is no collision warning and that in order to shuttle you have to "target" your destination as for attack (which was not so obvious for me, some in game help would be have been really helpful). So I got my first job, which failed because the time limit was reached. Second mission the same thing. Even at full speed I don't see how I can manage to travel through two systems in about 80 days. What do I do wrong??
I wanted to see how combat works in starfury as this will apparently be similar in SE V but I am a little bit lost and frustrated with the starfury demo.
Any help is appreciated.
