boot camp partition still too small

When i first partitioned my drive to install bootcamp I gave it 40 gigs of space, this turned out to be too small so I made a backup, and repartitioned my drive with 60 gigs for the bootcamp partition. I reinstalled windows 7 and then restored my old windows volume, but it still says the bootcamp volume is 40 gigs instead of 60.

what should I do? I made a bigger partition but for some reason when I restored my old windows volume it shows only 40 gigs of space for windows and dosent show any extra space, although in disk utility it says the bootcamp volume is 60gb like it should be
