You can check your WHMCS portal under the "Configuration" tab.
To check WHMCS Click on "Servers" and ensure you have an entry in this section. If an entry already exists ensure all the details are correct such as: server ip, type of control panel (cPanel, plesk, hypervm etc), name servers, your server root username/password etc.
For the automated emails- have you set a cron job for this?
Anyhow, if you are using a WHMCS software, you should call them or go through *their community forums for more details.
