My user account is missing
If you cannot access your user account and can't retrieve it using the "forgot password" option, it is likely that you have not created one yet. The accounts system is relatively new, and we haven't linked any previous purchases to the accounts system. If you would like to create an account, you can do that by registering here.
Once you have registered and verified your e-mail address, add your Reference 4 activation key, you will then be able to manage all of your active computers yourself and deactivate any unused machines for a license transfer, should you need it.
