Hello Zakiroyhan,
If you need to reactivate your registered license(s) after reformatting your drive, please download the latest eLicenser Control Center (eLCC) for your OS (Mac or PC) to your refreshed or new computer.
Then log into your MySteinberg account.

Next, look under My Products, and select a license you wish to reactivate by clicking on the down arrow on the right to see further Details and select the option Software Reactivation.
You will be asked to enter your new Soft-eLicenser number.
To copy a Soft-eLicenser number, open the eLicenser Control Center (eLCC) which can be found in the “Program Files” (Windows) or “Applications” (Mac) folder. Select “Registration” from the top menu, choose the 20-digit Soft-eLicenser number and click on “Copy Serial Number”.
Please note, If you registered the previous license it will auto fill your previous registered activation code in the old activation code field. Once the new Soft e-Licenser and old activation code fields are complete select Reactivate. This will provide you with a new 32 character activation code(s) for any license(s) you need to reactivate.
To reactivate the license on your Soft-eLicenser, open the eLicenser Control Center (eLCC) which can be found in the “Program Files” (Windows) or “Applications” (Mac) folder. Click on the green “Enter Activation Code” button to enter or paste your code. A valid code entry automatically displays the license to be downloaded below.
