It does not work about menumeters

[monterajp]

Hi there, I answer myself ;-)

Although I think my system were working well, I've downloaded again El Capitan from App Store and I reinstalled the OS. All is working fine as usual, but now MenuMeters too.
I think something was wrong although I don't knew what it is. As curiosity I have to say that at the first boot after reinstall it appeared a window, like every time an App is launched for first time. I agree the notice and MenuMeters App started work.
I hope this can help to anyone with a similar problem.
