Akiruz you are good to go

first put the serial, and asked to put the other registration number

 
This serial number has already been registered to you previously. You do not need to register it again. You will need to enter this code into your product to unlock it if you have not done so already. 



For your records, your registration code is the following: DE7C-F5FC-XXXX-XXX

Please note: This code is case-sensitive and requires the dashes. If you are running Windows Vista or newer, your product may require that you run it as an administrator in order to enter this code. This can be done by right-clicking on your Cakewalk product's icon and selecting "Run as Administrator". If you cannot type your code in or it is not accepted, please try running as an administrator. 

For future reference, you can locate your product registrations at 
 
 
When I add another record number appears this msg
 
The serial number you have provided is not a valid serial number. Please verify that you have typed it correctly and try entering it again. Also please note that third-party serial numbers cannot be registered with Cakewalk but instead must be registered with the product's manufacturer.
