Cubase LE Activation- elicenser has been deactivated

I have an activation code for the CUBASE LE program when buying an Alessis desk, but I can’t install it on my PC, the activation code always gives me an error (At least one of the elicensers used during this process has been deactivated and cannot be used for more license transactions).
I would appreciate some help so I can install it.
