I'm running Windows 7 64 bit, unfortunately there is a problem with Cyber Face Converter and windows 7. I needed to get VMWare to create a virtual machine (basically a second computer in my harddrive) and installed the Windows xp sp2 OS. From there I was able to use Cyber face converter and just drag and drop from my second computer to my main one.
Another thing you can do is if you have a second computer in the house or even if you go to the local library and use a computer with Windows XP, you can just use a USB flash drive to bring the pngXXXX.iff file to the XP, uncompress it with cyberface converter, take out the images and save it back to the USB flash drive, go to your main computer with photoshop and screw around with the faces until you're happy. Then take the .dds files back to the USB flash drive and go to the second computer. Insert the textures in the .iff files and then take those .iff files and put them in the NBA 2k11 files folder....whheeewwww!
