I've been playing NMRIH for about 3 weeks now and haven't had a single problem since today's steam update. Everytime I try to play it, it goes to the game's loading interface and exits. It displays the Engine error - SetupArrayProps_R: array prop '(null)' is at index zero. I uninstalled and reinstalled steam, source 2007 sdk and the full NMRIH 1.06v full client from the installation guide and still have the same error.
Please help me resolve this error.
