please log-in to your MySteinberg account and use the unused activation codes instead that you can see under the “My products” section. Unused activation codes are marked by a sand clock icon on the left. If you are using a Windows Environment, you might need to install the newest eLicenser Control Center software separately from here: http://www.elicenser.net/en/latest_downloads.html. If your operating system version is not listed there, please use a legacy eLicenser Control Center version from the Archives: http://www.elicenser.net/en/download_archives.html
Then open the newer eLicenser Control Center and use the “Enter Activation Code” feature to download the Cubase LE 4 license.
