I don't know what happened, but now I can't get Disk Utility to start up anymore. It gives me a message that says "Error starting Disk Utility Background Process" with text under it that says "Disk Utility started, but a background process needed in Disk Utility didn't start properly. Please quit and restart Disk Utility." I try to quit, but the program does not respond, and I end up having to force quit it. Can anyone tell me what's wrong?
