How can I fix my Matsui DVDR100?

My Matsui DVDR100 had a power cut whilst recording. When I switch it on and try to get past the 'Reading' sign a prompt comes up saying, 'Power failure detected, attempt to recover last recording' - 'Confirm' 'Ignore'. 'Confirm' is highlighted but the remote does not activate it, or move to highlight 'Ignore'. In fact, I cannot get past this point. Any ideas to unfreeze it, please?
