Richard, Thankyou for listing the link for AIRAC 0311! I uninstalled the planes and switched to 0311 before trying it. I then started FS2004 and loaded the 737, it worked perfectly. I exited FS2004 and tried it again, and it crashed to the desktop! Very strange indeed! I now have no clue as to why this is happening! It only does this with the PMDG planes. This is not a criticism PMDG, just an observation. If anyone has any ideas, I'd love to hear them! Thanks,Bob Kelletthttp://www.opticsmall.com/VirtualAlaska/737700-.jpg

But I decided to change to Airac 0312 , and it crashed, and I couldn
