Does the new hard drive contain all of your own files, or is it a completely new install of the operating system? If it contains your old files and user settings, then your login information is already set, and you most likely have AutoStart enabled. Do you see an iCamSource icon in the Dock or in the menu bar? The stable version will have an iCamSource icon in the Dock, whereas the BETA version has an icon in the menu bar.
