Licence not loaded

I lost my system after formatting and installing a new windows ,when I install the licence and run it ,I get the error saying the file is correpted & unreadable and I am pluging the key correctly

I installed the cube when I run it I get “this computer is not registred for this software,please reinstall”

I reformatted and reinstalled windows now when I install the licence to be activated I get this error “Software activation failed .cannot communicate with the activation server”
