Since you just installed the board new, I say that you need to go into the menu to load default settings. Once you reboot, your error should go away.
You have two paths forward.
If neither of those fix the problem then you likely have an issue with the ICs dealing with digital logic and the signals handling the ~MEMPROTECT signal.
