    first off put the lever in the low gear position ,then loosen the 5mm allen key or 9mm nut which attaches the cable to the front mech ,pull the cable hand tight and retighten the fixing bolt and see what happens you will not do any damage

    Really stupid question I know but since I've made this mistake before I thought I should ask - is there any mud/twigs blocking the dérailleur from fully descending?

    If that's not the case then check out http://www.sheldonbrown.com/derailer-adjustment.html specifically the section on the front mech lower limit screw.
