Carleree,
If this happened to me, once I had working email again, I would requery those I hadn't heard from, with a short explanation. If they haven't responded yet, they can disregard.
I would think the slightest possibility that you missed something would make this the best course. The situation would drive me nuts, anyway. Something similar happened when an exclusive ended without me hearing anything, I emailed, and then my phone went on the fritz. (Oh, the benefits of having Verizon Fios. When it goes out, one loses telephone, Internet, and TV at the same time. If you're unlucky, your damn battery also starts screeching every 15 minutes. They told us, "Oh, yes, sometimes they do that.")

The editor wants chapters. Here goes nothing... I'm trying not to get my hopes up too much, given my track record. At least, he understands the basic premise of my book and hasn't been turned off (yet). I'm sounding like Eeyore, aren't I?
This comes just in time. I'm out of town visiting relatives. It will be great to tell them that an editor is reviewing my book now

People tend to say things like, "Well, you've written this book. When is it coming out?" or "Is it on Amazon?" Such comments are usually followed by, "You know, you could self-publish..." My usual response is to groan and take a hefty slurp of whatever drink is available. I need a better response, I suppose.
