Genesis version 1.* had an option to either use a Text version of Image as the Logo on your Site, since you have upgraded to the latest version the 2.0+ there is no such option and you might need to do the following to add the logo like me.

1.) Login to your WordPress dashboard.
2.) Go to Appearance >> Headers. You will see there you can add only the header image and not the logo, so there we will use Genesis Simple Header plugin.
3.) Uncheck “Show header text with your image” and hit Save.
4.) Install and activate the genesis simple headers plugin from the plugin Menu.
5.) Go back to the Appearance >> Headers.
6.) Select “Advance Mode” under Genesis Simple Header Title.
7.) Set the Custom Width and Height equivalent to the Logo Image width and height and Hit Save.
8.) Now upload the logo and hit save, you may not need to crop it.

Enjoy!
