3 x Java Web Start and 2 x installer. With installer I could play. After closing the same problem. Used installer de 2e time I managed, when it was still open, to create a shortcut and now I can play. Icon(2) but there is no first one. New downloaded libraries won't open.

After update 5.2 the icon disappeared. There is no shortcut, no .exe and no way to start. HELP
