NPCharacter Error Message

[Short Jack Gold]

I am trying to increase the number of soldiers in the battle scene (Hornblower)

I get this error message when one group should be loaded

RUNTIME ERROR - file: characters\characters.c; line: 121
Cant create class: NPCharacter

The line referenced is :
CreateEntity(&character, character.model.entity);

Could it be anything to do with the quantity?
I get NO other errors at this point.

I think I had that error message some time as well <img src="style_emoticons/<#EMO_DIR#>/unsure.gif" style="vertical-align:middle" emoid=":?" border="0" alt="unsure.gif" />

I'm afraid I can't remember how I fixed it though <img src="style_emoticons/<#EMO_DIR#>/sad.gif" style="vertical-align:middle" emoid="" border="0" alt="sad.gif" />
