I installed iWork, and it works just fine. However, now I cannot open Word, even if iWork isn't open. Everything freezes up, and I just get the endless spinning rainbow. Force quit won't open, and the dock is unresponsive. It stops when I shut off my computer, but I still need to use Word! Anyone else have this problem, or know how to fix it? ps. I'm running 10.3.9. I have a copy of 10.4 but have not yet installed it.
