Man...I tried to play when I came home...My game don't work anymore...I tried to backup the save files, and reinstall, but same problem...The game close...Any help? I am with a lot of good weapons, almost 10 dwellers full stats! I don't want to start over...

When will Bethesda patch the game, to recover our save files????

Your save file might be gone forever. See http://www.gamesas.com/topic/1536698-game-crashes-on-startup/#entry24334602
