lost dongle and very stressful not sure what to do

let me start from the beginning
i have lost 2 dongles and have a third im trying to get working

they have marked the first dongle as lost and i activated the zero down time and have lost the second dongle which contained the zdt and i need to have my license on the third dongle as i am out of zdt and i cant use cuebase

i need to mark the second dongle as lost but the zdt icon is grayed out and says i already used it how to i disable the second dongle so i can activate the third dongle and continue creating music?
