That really sucks. Have you tried looking for your recipes.bsmx file and using the import option? Hopefully it just didn't load properly and needs to be imported manually. If that doesn't work, then try another system restore and then import.
I saw the notification about the update but didn't pull the trigger yet. This is a good reminder for everyone to backup your recipes! I think I will start printing out a physical copy and putting them in a binder as well. It's so easy for digital data to just go poof. I lost my entire library on Rhapsody that way (about 3 years worth of discovered music) I almost cried. I'm sure some of that music will never grace my ears again, and that makes me very sad.
Good luck, and keep us posted.
"Far better is it to dare mighty things, to win glorious triumphs, even though checked by failure...than to rank with those poor spirits who neither enjoy much nor suffer much, because they live in a gray twilight that knows not victory nor defeat." ~Theodore Roosevelt
