I had the same thing! IF you have a NVIDIA graphic card installed, this is what I did to make it work; search for opengl files from the Windows start menu, delete your nvopengl.dll file, BUT make sure you have a file called opengl32.dll and/or opengl.dll in your Windows/system directory after you deleted the NVIDIA openGL dll file. Start Vue 4 again and see if it worked. Make sure you have OpenGL activated in the options. If this solution did not work for you, you can deactivate opengl world browser in the options and contact e-on software! Hope it works out for you!
