Sscherin,
I did the update at work in 5-10 minutes.. Your DL times may vary.. We have dual DS3's to the net
Is your G3 installed at work? Do you have a way to transfer the install from work to home?
Near as I can tell, G3's support doesn't offer a way to download an updater. You have to "download" through the installer and that updates the program. Users can't get a copy that's transportable, only an updated install.
