Firstly, contact their customer service helpline (LOL) and ask for an explanation. If none is forthcoming, (or given to you in rapid gibberish from an offshore call centre), then cut your losses and invest in a decent piece of kit. I invested in one last year (can't give you the brand name in case it contradicts AB's strict advertising code, but the name is shared by two former US presidents and purchased from a catalogue store named after the one hundred-eyed god in Greek mythology). It cost just short of £100 but gives you 120 hours of recording (although the actual figure is nearer to 160). Best investment I ever made - when I returned home after spending a fortnight in hospital last summer, all 14 episodes of Corrie were ready and waiting for me.
