Unable to activate Cubase LE

I got a cubase 11LE license when I purchased an audient evo 4 studio pack. Yesterday I tried installing and activating on my mac and I my computer crashed before registering the product. I was now trying to install it on my windows computer and I am unable to activate the product. It says that the activation code sent to me is already used

Hi and welcome on the forum,

Then reactivate the license to the new system, please.
