HWRM 1 campaign crash

I can open the game and the menu. I can play a game against the computer. But when i try to start a campaign it goes to the loading screen, then to a black screen with the audio playing before crashing to desktop. I can play the multiplayer and the HW2RM campaign so don’t understand why it is HW 1 RM in particular. I am running AMD Radeon HD7800, and Intel i5. I updated all teh drivers with no luck.
Many thanks
