I had highlighted 13 rows, rightclick format bars and was getting the spinning wheel for "thinking". I had noticed that there was a (not responding) message in the programs window bar the the top. I figured it was a good time to take a two minute break. When I came back there was a new blank project on the screen. I checked the recently opened, and all the mpp files, all my work is nowhere to be found...... 8+ hrs gone....

I'm not positive but I believe I started the day by saving a new version of an old file and started the update.

Anyone with any ideas?
