Counterwallet not sweeping in my funds for some reason.

This is my balance: http://www.blockscan.com/balance.aspx?q=1HgCn9B5BaYJK4WwvRPANfpdq2rJ82CaMA

And I followed these instructions: https://www.youtube.com/watch?v=P33jqIjg67E

But when I put in the address and click Sweep nothing happens. Also there is no extra box that appears that asks how much I want to sweep. Any help would be appreciated!
