.Map :: MoHAA Mapping

G'Day i new to Mohaa mapping and when ever i try to palce an AI in my map i get an error message saying

"skeletor CacheAnimSkel, anim models/human/animation/scripted/t010/00a001_victory.skc has wrong header [(indent,version) = (1312901971,14) should be (1312901971,13)]"

What does this mean?

That you have to download the Spearhead 'SDK' or rename your mainta folder to something else.
