In general there are 2 scenario's that trigger such an email:
You are using the same credentials for different 'clients' or you forgot about an earlier registration and you entered a (slightly) different name.
The registration server will recognize the duplicate email (for instance) but will complain about the fact that you are using credentials that belong to another client.
You are asked to check it and reply to the email with a reply.
You 'own' commercial licenses but you use credentials that are different from those on our registration server.
For security reasons we only send out licenses to a registered email address. When the registration server is unable to match the data it will send you an email and you are asked to reply to it.
In general we will not honor such a request and ask you to go through the person registered.
A few TIPS:
1. Store the license confirmation email and or the attached license files;
2. Communicate within your organization who is responsible for requesting licenses;
3. Make a backup of the credentials that you entered (although the Components Manager will always store the credentials you last used);
