Como Saber A Quien Pertenece Un Numero De Celular En El Salvador

HI,
Looking for assistance.
I uninstalled Nitro Pro 13 from my machine due to it being always crashing, and re-installed the software, but every time that I try to activate my license it says "the serial number entered does not exist".
I am using the same serial number I received when i purchased my license thru Cleverbridge.

When I use the support ticket for activation and go thru the required process, I put my license and it does recognise it.
I get a table that shows my license is for the 13 version,
