Soft eLicence missing, installation helper doesn't fix

Need your help. My eLicenser doesn’t show any soft-eLicenser anymore. I already tried the installation helper with no benefit (I uploaded a video here: https://1drv.ms/v/s!AgSuOUOSZkcwjcBI6jzELdMIu-6BVQ?e=GQVt05). I cannot use my licenses at all: can somebody help me?
