First look into New Member Information and follow the recommendations (==reading some more topics) until your user-account is levelled up to basic user.
Than you can add your current project (kicad main manager–>File–>archive project). Without the project-files all hints/tips are only guesswork.
Nevertheless one guess at the end: do you have used really “route tracks”-command to connect the pads in the board editor or only the simple “draw a line”-command? The latter will not work.
