Same here on #1. They have just made an update. For whatever reason, it's not connecting to allow the updates. It's probably not anything you can fix on your end. I imagine it will be very high priority to fix, and will probably 'suddenly' work again tomorrow - so unfortunately this means a little waiting.
Problem #2 may be connected to the above. Perhaps wait until tomorrow. Assuming you can then update correctly, try and run the game after that. If it still doesn't work, then people will offer you further help. If it does work, then I'll see you around in the wasteland
