Reactivate MP3 Encoder

Hi at all, two yers ago i installed the MP3 encoder. The evaluation period is obviously expiered and now i need to reactivate it. For do this, is it correct to go on MySteinberg/Reactivate MP3 Encoder?
Why this page ask me " New Soft-eLicenser Number"? Or maybe i have to put simply the number of my soft-eLicense?
Thank you in advance.

If you don’t have tthe full CB version, you have to buy it after expiration.
