First impressions: 737NGX Tutorial

I'm still working out how to fly the big planes, so I followed the tutorial. Great work, PMDG! I've been following a few of these tutorials, and this is the first one that actually taught me something and allowed me to finish a full flight first go. Most of the other ones I've done for other 737s have required a bit of work to finish. However, a couple of small things. First, the SIDs/STARs aren't actually in the document as promised on page 15. Second, I couldn't get the HGS working following the instructions in the tutorial. Mind you, I haven't been able to get it working full stop, so I suspect operator error. (Update: Corrupted DLL.XML was the problem). One other point, unrelated to the tutorial: I'm finding that when I save and load a flight the plane configuration gets completely lost at least some of the time. I had a look in the manual and didn't see any special button I should be pressing, so does anyone know what I'm doing wrong? Robert Ewing
