Hi Tom,
No change there. Sounds like the map area has not been defined, and you can just see the tracks in the define map view? Try redrawing a small area over the tracks and see if you get a map in your contour and 3D views.
One other possibility that I can think of is that your map is in vector mode and the depth range of the map is not big enough to include a single major contour value (all maps default to vector mode when first created, and upgraded workspace projects will be in vector mode until they are changed). In this case, there will not be any isobaths (depth area polygons) created, and you will get a blank map (although you may get some minor contours showing).
Try changing the Colour mode of the map to Raster (in the map settings) and see if a map appears in the contour view. If this is the case, then you'll need to set a smaller contour interval to get the map to show properly in vector mode.
If none of that works, please post some screen-grabs of what you are getting, along with your map settings, and we can take it from there.
cheers,
Matt
