Disable activated computers after reinstall of windows

I’m using GP for a year now, and very happy with it. My previous laptop had some troubles running stable with all effects and sounds, despite some reinstalls of windows. So I bought a new laptop, with better specs. I tried to active GP but got the message that I had too much activated computers. Only then I found out I should have disabled GP on my previous laptop, before reinstalling windows. So I have just one activation left, the other ones I’m unable to deactivate, because I reinstalled windows.
Is het possible for you to delete the current activations, so I can install GP on both my old laptop (for backup) and my new laptop?
Thanks in advance!

You can raise a support ticket for that.
