I have just done the "update" and now the game crashes every few minutes - it doesn't seem to matter at what point (even during walking) and it is so very frustrating coz the game is amazing. Before the update, I hadn't come across any problems with the game! Now I wish that I hadn't done the update. Is there any way to "undo" the update? Dying to play the game again! Please help! Thanks! :fallout:
