Originally logged in on Cmap genesis on my Lowrance HDS carbon. The Cmap screen appeared, now I can’t login, the message appears server error in ‘/‘ application. If I try to reset my password the message email does not exist in GoFree. Tried to resign up again but message comes up as the my email is already being used. So how do I sign in to C-map genesis?
