I just loaded up the latest version of 4D (thanks Nick for the help), but I can't get the weather grib to show up on the maps (ENC or C-Map). The grib file is in the folder, but the usual overlay doesn't display and when I try to run an optimal route, I get a message that says "No wind at start." What am I doing wrong? The older version had an "x" that would turn off the weather, but that seems to be gone from this version. Thanks.
