Dunno what you've done there but you should have all the arit files .nif .fx in a folder called mi24 then put that folder in
C:\Documents and Settings\***USER NAME***\My Documents\My Games\Sid Meier's Civilization 4\CustomAssets\art\units
then edit
C:\Documents and Settings\***USER NAME***\My Documents\My Games\Sid Meier's Civilization 4\CustomAssets\xml\civ4artdefines.xml
so it reads
Code:
<UnitArtInfo>
<Type>ART_DEF_UNIT_MI24</Type>
<fScale>0.5</fScale>
<fInterfaceScale>1.0</fInterfaceScale>
<NIF>Art/Units/MI24/mi24.nif</NIF>
<KFM>Art/Units/Gunship/GunShip.kfm</KFM>
<SHADERNIF>Art/Units/MI24/mi24.nif</SHADERNIF>
<ShadowDef>

<ShadowAttachNode>BIP Pelvis</ShadowAttachNode>
<fShadowScale>1.0</fShadowScale>
</ShadowDef>
<iDamageStates>4</iDamageStates>
<fBattleDistance>0.5</fBattleDistance>
<fRangedDeathTime>0.12</fRangedDeathTime>
<bActAsRanged>1</bActAsRanged>
<TrainSound>AS2D_UNIT_BUILD_UNIT</TrainSound>
<AudioRunSounds>
<AudioRunTypeLoop>LOOPSTEP_GUNSHIP</AudioRunTypeLoop>

</AudioRunSounds>
<SelectionSound>AS3D_UN_GUNSHIP_FORT</SelectionSound>
<ActionSound>AS3D_UN_GUNSHIP_FORT</ActionSound>
</UnitArtInfo>
note spacing not right in here
