I know, I've been struggling with the problem of the screen for a long time, I just want to say that if it only happens to me it's not a problem, in this case the models have been solved because you need to install the Visual Redistributable c+++ 2012. But no one has any idea what's going on, especially the one developing the program. The beta version has changes in the exporter that needs Redistributable libraries, but I suppose the good thing is that it has been fixed and since windows 10 the exporter is working correctly from the map editor.
