I have a Radeon HD 5700 on Windows 7 Ultimate SP1 64bit.

Game worked fine during beta until the last update. Phase 4 I believe.

Now whenever I click Play from the launcher, a black window appears (game window that always appears), then it crashes.

Have tried updating video drivers to latest official, then to latest beta.
Uninstalled video drivers, deleted driver files, then reinstalled drivers.
Uninstalled virus software.
Uninstalled/reinstalled game (including manually removing files/folders not removed by uninstaller).
Did all Windows updates.
Tried going to my other PC (which works), loading the game, turning everything to lowest settings, then copying the .CFG file to the non-working game PC.
Also used that method to disable and enable Window mode.
Tried running in various compatibility modes and as administrator.
Disabled sound in game and disabled sound drivers.

Still crashes.

Thanks for any advice!

Here are the various errors I get.
