problem

Hello, I am on win7 (run game as admin, no anti virus, no extra firewall) and after I login, the game downloads some unitxt file and when I press enter it closes. Once I restart the game and logged in, the same process repeats, any solution? Thanks

The title menu music will work but once in the game the sound cuts out completely. If I stand still for long enough it comes back sometimes, but quits again if I move. I need help!
