I just restarted the test and when I ran out of time on the third section I ran into the same error. 

This has now taken up 5 hours of my day, and I lost all my progress again. Unless there is a fix to resolve my problem I will not be returning to this website ever again. 

Hi Quinton,

I'm sorry to hear you're experiencing this issue!

Could you please submit a support ticket so our team can take a closer look at the issue?

Thanks!
