Although you have changed your password, the newsletter and subscription to emails is still registered to your new account.
The only way to fix this is to stop the emails coming from the old one, and register your new one with the newsletter.
Step 1.
The next email you get to your old email address, scroll to the bottom of the email and look for manage my subscriptions.  Click on that link, then delete all subscriptions.
Step 2.
Sign up once again on the training you originally signed up here.  It will reset the emails to your new password.  If it does not allow you because you are already a member, email us here from your newly registered email address on this site and the one you wish to receive the emails too.
Note that you must still confirm your subscription to that email address by clicking on the confirmation link you will receive once we have added you to the newsletter.  This is to prevent people from putting email addresses of other people to annoy them.  It is required by the CAM Spam laws, and we fully comply with proper newsletter regulatory laws.
