Well guys, few days ago I tried opening iChat. I saw no window. When I toke a look, I saw that there were no accounts(just like if I hadn't added any). I couldn't open the preferences panel too or add an account to it. Then I trashed iChat and files related to it(such as preferences) and installed it again from the Mac OS X Install DVD. I could login again, but now I can't send messages. I hint enter, but nothing happens. It used to work. Any help is appreciated.
