Thanks for the help. I updated Airport Utility to the newest version, and now I can open it. However, when it scans for networks, it comes up with nothing. It says, "AirPort Utility was unable to find any Apple wireless devises. Make sure the Apple wireless devise you want to set up is plugged in and in range of your computer, and then try again." I hit "Rescan" and it still comes up with nothing. What should I do now? (and thanks again for all the help. All this stuff is confusing for me.)
