System Failure!

I turned my Macbook on this evening and everything was different. It was like someone stole my computer and replaced it with a different computer that doesn't really work now. A lot of my files were still there, but some were in different places. The more I try to use it the worse it seems to get. Worst of all. My backlog of e-mails and contacts from Microsoft Entourage are gone. I will be at the Apple Store as soon as it opens. We are now without skype, and thankful that we still have our Toshiba. Where is Mila Thomas when you need her?
