BL GOTY Enhanced Steam edition hard crashes on loading Hallow's End

On playthrough 1 with a save file imported from BL GOTY non enhanced. Have already beaten Destroyer. Jakobs Cove loads and runs fine. When I click to enter Hallow’s End on the hunt for Ned quest, I get a hard crash to the options of “search for solutions online and close” or just close program. This is the error info I get:

  • yes, I have verified my install files. Still crashing.
  • I already tried copying cudart.dll and creating physxcudart_20.dll. Still crashing.
  • I’ve done all this as administrator including running the game as administrator.
  • the crash only seems to happen for Hallow’s End. I’ve not seen it on trying to load any other area.

Running Win 8.1 64-bit. System specs are elderly but sufficient to run the game on medium settings at a halfway decent fr. Made it through the whole game up to and through Eridian Promontory so unless Hallows’ End is intensely demanding the problem is not likely to be hardware.

Any help would be much appreciated!
