Alln of my Easyeda projects are now messed up.  When I open a projetc and go to the PCB file and try to render a 3D view, all I get is a PCB with not components on the board in teh 3D view.  This seemed to happen all of a sudden and is across the board for all saved project and also happens when I create a new project.  I and using EasyEDA std desktop version V6.5.51.  PLEASE HELP!
