I never said you were stupid. Plenty of intelligent people miss that. I can attest to the fact that people sometimes get very caught up in doing something (i.e. asking for help on the forums) and ignore everything else.
Anyway, which update guide are using (Java or Manual)? What OS do you have (10.2.x, 10.3.x, 10.4.x)? And are you an admin? If using the Java updater, post a log from that here.
