Issue with FlowArm PLTW license key

Hello
I am new to this class which used the FlowArm application last year - but we are now experiencing a window that states to enter an Activation Key for the app to work.

I don’t know the activation key? Where would I find this?

The license for the class was temporary to allow teachers taking the course to install the software on their computer.
