Jp-Scene erroneous override of mod_menu

Hi,
on Scene template, reached Template>Scene>Customise>Create override I hit inadvertedly "mod_menu" in te menu list. I got back a succes message (something like Succesfull override). Now I wonder if I demaged something, If I have to restore my last back up and wich are consequences of my act. Also, please, Wich way I can restore the previous native status of "mod_menu". Than you a lot.

Install the template again and remove the folder > html/mod_menu
