When I purchased my Macbook Pro about a year and half ago I clicked open the ichat icon from the dock to check it out. From what I remember an account setup window appeared. I wasn't going to use ichat at the time so I closed the window without doing the setup. Now I want to use the ichat feature so when I went to click on the ichat icon from the dock nothing happened no account setup window appears. I tried opening the ichat feature from my applications folder and again it won't open. My question is what do I do to get the ichat account window to open so I can start using ichat?
