My game wont start a new game or load any old saves. I can open the launcher and get through to the selection of new game or load game or continue, I click on one of the options and the game just closes without giving me any messages or anything. I have tried verifying the integrity of game cache and tried reinstalling Fallout 4 but I still have the same problems. I know my computer can run Fallout 4 because I have already played 25 hours and updated my video card drivers
