First: im also just a normal player as you.
well, there seems to be a technical problem. If i go to the spectate page, i see races from 3am local time (this is 7 hours ago). So there seems to be an issue with the simulator. i guess Jack will postpone the affected races to the next calender slot (like here:

But this game is just a very small team and located in europe. So this issue happened in the middle of the night. Just be patient.
