Cant find robots, process, Machines under orchestrator

Hi,

I have to finish my advance level 3 exam but my orchestrator is not working.
It says subscription is expired which is right as I activated long time ago and I do not know how to do and what to do now.
As orchestrator is not showing me Processes, Machines, Robotes and other related options on left side and I have no attended or unattended robot.

Meanwhile I reinstalled PC due to some issue of virus and I have installed community edition 2019.8.0.

When i try to connect to orchestrator it says “Invalid Machine Key”.

kindly help what to do.

can you post the screen which you are getting when you try to login to the url platform.uipath.com
