There appears to be some issues with your connection and/or PC.

Could you try:

• Check your internet connection. You need at least 2mbps/2mbps uplink/down link to load the simulation page.
• Check that you are not behind a VPN, firewall or proxy.
• Try the Firefox or Microsoft Edge browser. You appear to be using Google Chrome at the moment.
• Check that you have at least 4GB free memory on your PC.
