The issue turned out to be that I had Prepar3D installed on an external USB 3.0 hard disk drive. The data transfer between the main internal C:\ drive and the external drive was insufficient to support the 737NGX. The problem vanished when I reinstalled P3D on my C:\ drive.

Thanks, I've just sent a ticket. The dll.xml looks pretty normal to me. I'm very curious about the debug log. Why won't the 737NGX 'update systems' once and for all?

Thank you for the reply downscc. I loaded a Mooney Bravo and changed the sound drivers from the automatic setting to the specific drivers, but didn't help. I installed SimConnect (three times) but that didn't help either. Actually, I'm not sure if it installed correctly - when I click on the .msi file a box pops up with a green bar for a few seconds then goes away. Is that supposed to happen?

Hi, Whenever I select a 737 model in the Aircraft selection menu, everything is fine, but problems start when I go back to the main screen. The aircraft model in the little window is rotating but at very low FPS (~4FPS - not normal). As soon as I click on any other button on the menu (e.g. Change Airport), the plane stops spinning and P3D becomes unresponsive. The program doesn't crash, it just hangs. I can load any other aircraft and start up the sim fine. But when I go to 'Change Vehicle' and change to the 737 and press OK, I just get a black screen. Again, P3D doesn't really *crash*, just nothing happens. Here is the debug log: I checked if the WAV files exist, they are definitely there. The number of "Update systems" lines seems to be proportional to the amount of time I leave P3D hanging. I've reinstalled P3D and 737NGX multiple times but to no avail. I haven't been able to load up the 737 in the sim at all. Help please! :( Thanks, Thomas Kobialka P.S. I did get a little message box asking for the license key the first time I loaded the 737, and that was fine. But after that I ran into the problems described above. P.P.S. I'm using Prepar3D v2.5 (newly bought yesterday!). EDIT: Jeez, sorry about the multiple threads! :o I kept getting an 'AVSIM is over capacity/undergoing maintenance" when submitting the topic. Guess my computer hates me today in particular...
