Hey everyone, I'm fairly new to flight simming and very new to the PMDG 737NGX. I ran into a problem today with ATC on VATSIM with reguards to my flight plan. I was told that the data in my FMC is out of date and that I needed to update it. What do I update it with, and how do I do it? I Installed SP1 but that didn't do it. Help please.
