All the way in at the Doombringer level which I have nearly finished. End of level boss killed - gravity goes. Got all the way back to the area with huge pipes connecting like spokes to a central hub. Gone into the 2nd from last doorway (as you would see it on the way back) and gravity is restored. I run through a doorway that had previously been inaccessible and the game cuts to a cinematic of a corridor which it being racked by explosions. The game then stops here.

 

It's not actually fully locked as the console can still be accessed (SHIFT and `) console commands can be typed etc..

 

I have tried reducing graphics to 640x480x16 and bilinear instead of trilinear

I have tried turning GL Extenstions off.

I have de-installed and re-installed.

 

All to no avail - is there a console command to skip past this cinematic or is there a more general problem here.
