License re-set and re-activate TRADOS 2017

Hi! I have a Trados 2017 license that I purchased years ago but my old computer "died" with the program in it and now in the new one I try to add my licence code and it says is not valid. I have downloaded TRADOS 2017 but I need a license reset in order to be able to re-activate the program on the new PC. Can you give me a hand? The free trial of Trados 2017 expires in 28 days. Thanks!
