SB FMS gives me this error when I attempt to go direct to a waypoint: "Are you sure that all squawkbox.dat files are in the same directory as squawkbox.exe" - All the .dat files are in the same directory - I've double checked that all waypoints are entered correctly I've been experiencing this problem when typing in most waypoints or Airports. Do I need to update my .dat files? What is wrong? Can anyone help? Thanks.

I am not a good one to answer SB FMS questions because I never use it. Squawkbox nav data can and I suppose should be updated.Richard Stefan kindly provides a very helpful free service in the form of regular AIRAC updates for Microsoft Flight Simulator addons like Flightmanager, FS-Navigator 4.x, EFIS98, FS-Build, PMDG 737NG, 767-Pilot in Command, PSS Airbus/Boeing/Dash8, Dreamfleet B737, Eurowings Professional, Squawkbox or Navdash 2.5.You can find Richard's site here: http://www.navdata.at/Click on the "AIRACs" link on the dark blue navigation bar.
