Activating Dongle for Cubase studio 5

I purchased a used version of Cubase studio 5 that includes the original license and dongle. When I tried to activate the license it told me that it was already activated. It also tells me that I have 25 hours of usage ?
Is there a solution to this ?

The previous owner already activated the license, so it should already be on the dongle, ready for use. If it isnt then the seller didnt give you the license.
