A: The first thing to do is to check the coordinates of the imported data points in Mapinfo. When all of your data points have coordinate values that are outside the range of acceptable values for a UTM zone, it will plot as a single point or as a line in Mapinfo. Then check if the coordinate system you are using in ioGAS is the same one as the one you are using in Mapinfo.

If the solutions outlined above do not work, we have encountered this sort of problem where the language of the operating system (in this case Windows in Portuguese) is not the same as the language used in Mapinfo and ioGAS (both in English). In this situation, the solution was to install Windows English language pack and change the language of the operating system to English when running ioGAS and MapInfo (Go to Control Panel | Region and Language Settings and then add English from Install/uninstall languages…).
