[Simulink] Cannot reopen world.

Hello guys, I'm trying to simulate a bouncing ball, http://prntscr.com/cmjszp here you can see wht I've done,

thing is after I closed it and opened it again to keep working I couldn't open the VR Sink anymore, and it disconnected from the VR Signal Expander block.

This is the error I'm getting: http://prntscr.com/cmjtf4

Any help please?

It seems like you did not relate a wrl file to the VR sink block. Add a new VR Sink block and double click. Once the proprieties window opens you have two options: 1) if you have the .wrl file save: just click on browse and add the file. 2) if you do not have a file, just click new. there the 3D world editor will open and you can create the wrl file, so you can reuse later
