In Billings Pro Self Server you are unable to add the license information in Billings Pro Server Admin.
Why is this problem occurring
This can happen if you purchased a Billings Pro upgrade license and have not added your upgrade license when prompted or there is a typo in the license key.
- In the Licenses pane of Billings Pro Server Admin, you must first enter the Billings Pro upgrade license and when prompted enter your Billings license information.
- The serial number and license code are case-sensitive. Please make sure that you enter the serial number and license code exactly as it is, or copy and paste it. Ensure that there are no blank spaces before and after for both the serial number and license code.
