Tony is having issues with Skype and his Mac. Leo says that he can delete Skype, redownload, and reinstall it. That's how Chris Marquardt got it to work. Microsoft is making serious changes to it, though. The chatroom says that there's a Tech Note in Skype support that says to be sure the OS is up to date, along with Quicktime. Leo says to just delete it and redownload and install it. It's probably a localized issue.
