Thanks, Christine --
This is a problem that happens now and then, and we're aware of it. It seems to happen when something causes a hiccup on the server, and we can't reproduce it at will.
If you should encounter the problem again, follow the instructions that Robin gave you and try to recreate the profile. As you noticed, that will sometimes bring up the "lost" profile from before, and you can adopt it and go from there.
We're continuing to try and discover what it is that's causing this to happen.
