Hey Kanetsu,
It's one of the major things we're trying to clean up at the moment - just not clear enough what you need to do at the start (the tutorial).
Essentially you are meant to go through doing all of Claire's requests until she tells you to go and check the other end of the plane. If you have difficulty, 'killing' her will end the tutorial too.
Are you able to describe what happened with the black screen issue? We haven't been able to replicate it, but definitely want to address it.
