Bob,
The map should come up automatically.
I have had some problems with getting the size of the map to auto adjust to the amount of space available (other modules, panes,admin screens, etc.)
Try deploying the module on a page byself.
If that does not work, you can go into the DDNVEDEMO.ASCX file and change the autosize parameters to smaller hardcoded values to see if yuo can get the map to fit.
map = new VE_MapControl(40.9521068, -73.592862, 10, 'r', "absolute", myoffsetLeft, myoffsetTop, mycellWidth,mycellHeight);
Change the four values on the right to see if you can get the map to show. First two place to start drawing the map, the second two are the size of the map.
An updated version of DNNVE is coming soon, hopefully to address some of the sizing and firefox issues.
