I'm thining about using this map for a video but all doors are invisible, help?

Error Vertex File for 'props_c17/door01_left.mdl' checksum 972034250 should be 145318345 (x2925)

I just checked, for some reason none of them have a material assigned, and I can't switch theirs/ add one either. I got CSS and the HL2 episodes, so it's prolly a map error

prolly css
