Simulation Failure

[Beardriuss]

I am extremely clueless when it comes to code or anything of the sort so the following lines I'm about to send you make zero sense to me. Thanks in advance for any assistance.
When I try to use the sim for my Blood Death Knight, every time I hit "Simulate" it provides me with this response:

After I hit "OK" to file the report, the system generates this link, which for me leads to the same window.
