Ok, I went to double check a recipe in my favorites to see exactly how much water to use, and it was gone!! In fact, ALL (about 20 - 30) of my saved recipes were gone but one!! Luckily, I found what I needed, but I can't remember each and every one I've lost. Has this happened to anyone else?

Yes it happened to a bunch of people. There's a thread on it in the technical support area of the forum I believe.
