If you receive the following error "This machine is registered to another user", this means that you have opened courseware on your machine using a different set of DRM credentials.
Once you initially provide a set of DRM credentials to open courseware, those credentials are then associated with your machine and no other credentials can be used on this machine.
You should never use another user's DRM credentials.
It sometime happens that a user has received courseware using one email and then subsequently received courseware using a different email (company email has changed for example). If this is the case, please send an email to firstname.lastname@example.org and provide the following information:
- Name of your machine
- The DRM username previously used to open courseware.
