I just downloaded Arena and I've found it really difficult to play because my logbook won't update so I have no idea what I am supposed to be doing. There is supposed to be something in my logbook, right? Whenever I go into it it just says that my logbook is empty. Please help!

Initially, you are supposed to ask folks where "Fang Lair" is.
