On certain computers when a mission is loaded, the simulation may not be visible to the right of the coding section, while the score/timer and other HUD elements are visible, as seen in this example below:

First of all, check that your Chrome Browser is the most updated version. Check by clicking the Browser menu mceclip1.png and selecting 'Help' > 'About Google Chrome'

If your browser is the most up to date version, there are several possible ways to fix the issue of the black screen. If one doesn't work, try the next one.

Note: You do not need to be logged into CoderZ to perform these steps, however you may be restricted by your local IT department, and would need to contact them if that is the case.
