Yes I had the same problem, having the downloader recheck your files seems to be working so far as I didn't get the unexpected error notice and the game is currently installing with no problems so far.

I think there seems to be some lack of respect for the developers and customer support staff trying to help people, particularly people like you. The game hasn't been released yet, and you aren't the only person who needs help with an issue. Learn to have some patience.
