From searching through numerous threads and steam community threads too. It seems (myself included) those with the AMD Radeon series have an issue when trying to start up the game. The 'Please stand by' screen appears and plays for a few seconds before closing (There is no error report)

I've tried the beta option, tried all different setting combinations, tried AMD catalyst (3D), disabled my anti virus, verified game files using steam, reinstalled the entire game file, device drivers and nothing yet. If anyone has any answers it'd be greatly appreciated! Lets hope a patch comes out for the less fortunate of those with AMD :c !
