You didn't lose your stuff the first time you ran the Combo, and you're not lkely to lose it this time, but as with all such stuff, it pays to have an up to date backup before you proceed.
Actually, Rita, re-running the Combo is a venerable and often successful troubleshooting step.
Good luck.
Okay, I don't know what to do exactly. d/l means delete, right? I could back it up on my external drive (which I do anyway) but then I would have to start up from my external drive should something go wrong, right?
So, since I'm not just updating for the first time, what are the steps to d/l and then download the combo? (I don't know as much as you think I do, apparently. :))
