As Byron said, we don't keep backups. You have to make them yourself if you want them. In the same boat myself...I made a backup before an update I did over the holiday last week, then forgot to actually download the thing when it finished... I'm now missing that backup, plus all the work I did Thursday and Friday, and all the new data that got collected by my software on Monday and Tuesday. Oh well...I always preach "make backups!", and didn't follow my own advice.
