Loss of your Internet connection will result in an error being displayed on your screen. You will not lose any of the decisions you have made from previous screens, but you will need to launch the simulation again.
If your current screen has not loaded, you will get an “unexpected error message”. Before contacting support, try to launch again from your home page, after checking your Internet connection.
This error message will also occur if you close your "Home Page" where you launched the simulation. Both your simulation screen and your home page must be open for you to remain logged in.
