3Dviewing error

I have a couple of recommendations:

1) Make sure that you have the lastest video card drivers installed.  The error message sounds like Global Mapper is having trouble getting its 3D display engine initialized.

2) Update your Global Mapper 16 to the latest released version?  You will need to scroll down a bit to find the version 16 installers.

3) If the problem persists in the latest version, please send a description of your workflow, a copy of your data (if possible), and the results to Blue Marble Geographics Support (geohelp@bluemarblegeo.com).  This will ensure that the support team will be notified of the problem and will expedite a solution.
