Hey, and thanks for the advice. Strangely, SP2 is NOT showing up on my add/remove folders list! I know I got a message indicating it had been installed successfully, but perhaps not? At any rate, some of my programs are opening fine, while others (e.g. FinalDraft, Wireless Internet, and ITuneshelper) don't ("application failed"). That SP2 uninstall file isn't where it's supposed to be, either. Any trick to find it? Or - is there a way to download sp4 on another computer, burn it to a disc, and install it over my flawed sp2? Please let me know. Thanks, Alex
