Hm, can you give us some more information?

Did you try to replace the scientists in regular Half Life, or in a Mod?
Where did you put the models in (in what folder)?
And was there a message when the game crashes?

Sorry for the late answer.
I can't say what the Problem is. I will look if the model will Crash my game too.
I know that scientist replacements for Blue Shift sometimes also crashes the game...
