        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

after going through loading screens my screen will turn white. I can still hear
music and gameplay, but the game itself is not visible.  Also while playing
multiple times the game will come up with an Unknown error and make me have to
restart.
