I had an issue after downloading the update and got an SDK error when opening FS2Crew in the 737NGX. Just inserted the two lines as listed below and it works perfect now.
Open the file below with Wordpad.
Microsoft Flight Simulator X\PMDG\PMDG 737 NGX\
737NGX_Options.ini
Add these two lines if they are not present in that file: [sDK] EnableDataBroadcast=1
