Beta patch did not fix this for me.
In fact, instead of getting the screen with sky/black, where I can change time compression, now the little crosshair with the plane appears, instantly disappears, and nothing happens.
Much worse.

Still the same for me.

Issue solved by beta patch for me

Now off to whine about the performance. Yay! :)

still no developer word? how many people still have this?
This is rediculous, more than a week now and I can't even open a game I have bought :\
A simple "we know it exists, haven't fixed it yet!" will suffice!

update fixed it for me. YUS!

Weird if it doesn't work for some... I'd wait for Steam to update your game (to make sure the patch is properly installed) and see if it works.

STEAM PATCH FIXED IT
STEAM PATCH FIXXEEEDD ITTTT!!! :D:D

also, over london, 22-30 fps max detail.
