I am logged in under a different ( old name ) because I was just using firefox, and it froze up on me.... So, I restarted my computer, and Firefox and Handbrake are missing from my dock. VLC is still here, as is the one other program I installed. Using Safari, my user name is now in red, and I can't log in. I am a mac noob. I just got my mac mini about 10 days ago. Any thoughts on what I can or should do?
