problem with reactivation cubase 4 essential

My hard disk broken!!!

when i try activate my key, i enter my activation code appears a message error: ""the license activation code has been used already.

An activation code can now be used only once to download a license""

i try reactivation but in the reactivation list not appears cubase essential 4, only cubase al & cubase le.

what can i do??? it´s important, i need cubase for my job every days!!!

thanks

You don’t need to reactivate, the license is already on the Dongle.
