At that time another spam attack on the blockchain happened. Your fee was so low that all the spam transactions had a higher fee and your transaction did not get included into a block. Which means no confirmations happened.

In the future, check out this website before sending a transaction: http://www.cointape.com/

It tells you if an attack is going on and which fee you would need to have your transaction confirmed.

It's not a great solution but at least a solution until a better solution is found against those spammers.
