i have a USB-eLicenser. i installed it. i have a license number. i created a new user account because i lost my Previous account.
please help me about how to register my eLicenser on my new account.
thanks

Hi and welcome on the forum,

If you had your USB-eLicenser registered in the old MySteinberg account, you cannot transfer it to the new one without knowing the old one.

The best was is to get in contact with the official Steinberg support and get your old MySteinberg account running.
