I have a private pension scheme and I missed out on being able to cash some in as I was 49 on 1st April 2010?

I have a private pension with a considerable amount of money in and I missed out on being able to cash a lump sum because I was only 49 on 1st April 2010 hence missing out by 2 months (I was 50 on 1st June 2010). As I understand it I cannot now exercise this option until 1st June 2015. Does anyone know if there are any exceptional circumstances whereby I could take a relatively small sum out?
