Hi,
If the DAT opens and you do not see any doctypes nor a license, it is possible that you are not being recognized as a DBXL Admin.
The Getting Started Guide has instructions on updating the permission groups to ensure you are an admin.
The trial license you installed probably expires on 1/15, so Hilary's email to you will be valuable, to extend your trial.
Let us know if you run into any issues or questions. Thank you!
