soft e-licenser problem

Hi, I recently had a problem with my computer and took it to Lenevo who replaced the motherboard. Now when I try to open Cubase a message pops up which says no license recognised. When I type in my key it says that key has already been used. Is this because of the new motherboard? Do I have to buy a new license or is there anyway to prove that it is the same computer?

Cheers.
