Remove the items to get the full version and enter the license key after it's registered.

After the program is registered, the menu items to get the license key and to enter a new license don't make sense. In my opinion they shouldn't be there at all after the registration is successful.

Maybe add in the about section of the program a note saying that it's registered so the user knows for sure, right now the way to know if going to that enter key place and seeing the "Get full version" button disabled.
