If you purchased a new license, from us or anywhere else, then that license is to CREATE A NEW ACCOUNT.
If you go to the login page and enter the information for your old account, then you will log in to your old account. If you wish to create a new account, then use different login information that is not already in use.
If you want to reactivate, change, or upgrade an existing account, please do so from within LASR X under account management.
Right now, there is no way to automatically apply a new license key to your account. You will need to contact us.
