While this sort of thing can happen from time to time in online games that get patched, my friends and I were enjoying trying to get through the main Campaign game and had been reloading a saved game, but now, since the game updated on steam, attempting to load gives the error "Load Error This save file was created with a level you do not have." Is there a way to get the previous level file back or was the Campaign file name changed and could be copied and named back?
