This has nothing to do with the batteries being low in my case, but an odd thing happen and I hadn't had the chance to write on this. I had no problem with the update at all, but when I sent a few mp3 files of a book to the unit, I disconnected it and tried to read a book. Well once disconnected I didn't get the normal "Bookport ready" message I have always gooten. I of course couldn't recall what the key sequence was for reset, so I had to pull the batteries out. THis solved the problem and its been fine ever sense. Gee I should keep a list of important keys like reset handy...grin My memory isn't quite what it used to be I guess...grin Scott
