Rick I think he is on about the Pilot log stops working in game, its the same promblem I reported and is a well know bug.
My log book has updated my flights for over 3 weeks now, even if I delete it and start a new one it just wont add any info to the lob book now about my flying time.
Rick the promblem you point too is if FSX crashes and you cant start the game, diffrent promblem but using the same item.
