Luis Bravo,
Welcome to LQ.
As hydrurga has mentioned, first make sure that your Caps Lock is OFF.
Ideally you need to refer to another computer so that you can easily follow these instructions for resetting both your username and password:

Insert the USB flash drive that you used to install Zorin and boot up the laptop, whilst
holding down the Shift key.
Select
recovery mode and then follow the rest of the instructions on the other computer.
Create a new username and a new password.
