if you are not trying to dual boot, what is the purpose of the resizing? – Bryan Sep 18 '13 at 22:30

Mounted partitions cannot be re-sized. Umouont the partition and you will be able to re-size it.

You cannot resize mounted partitions. To resize your Ubuntu partition (or any mounted partition for that matter) you will need to boot into a liveCD/liveUSB. From the live environment you should be able to resize your partition to your hearts content. hope this helps!
