I don't play the game about a mounts after last update, it's usually normal and playable but now it's stuck at opening Loading screen after sega and amplitude logo pops up

Help Stuck, game cannot start 

I have exactly the same problem, since the last update.

What are your system specs? Please upload a file that has the output from Steam-Help-System Information

Also upload your dxdiag as well

I removed version 17.4 of my Radeon 7700 series video driver and reinstalled my much older version. It resolved my launching bug.

Hi there's a new beta that should address issues with the 17.4 drivers

If you haven't downgraded to 17.2 yet, please try this new beta patch and report if it resolves your issue

For others if you could reinstall the latest 17.4 drivers and report back your findings
