I've checked very carefully, and the file is in the right path/location. Any suggestions?
Oh, really? Where did you find a "Civ3PTW" folder?
This is an example of the problem CIv3 Complete has finding the resources for scenarios. The scenario file (xxxx.bix) has told Civ3 to look for a file. It has supplied the following path:
Art/Units/../../CIV3PTW/extras/Medieval Japan/Art/Units/Otomo Spearman/SpearOtomoRun.amb
This means:
1. Start in the home directory of the Civ3 PTW or Civ3 Complete application. If you are using PtW I'm going to assume that you have moved that out of "Unsupported Extras" and into "Civ III Complete".
2. Go from there to the Art/Units/ directory.
3. Move up two levels in the folder hierarchy, which gets you back where you started
4. Move down from there through Civ3PTW/extras/Medieval Japan/Art/Units/Otomo Spearman/SpearOtomoRun.amb
This sequence fails at the second step on a Mac. Look in your Civ III Complete folder. There is no Art folder at that level. There are several folders that contain Art folders, but that puts Art one level down.
The safe answer to this is to wait for Aspyr to release their patch for Civ3. That's what Brad recommends.
I'm altogether more cavalier than Brad

. Hey! What's the worst that can happen? You have to reinstall Civ3 Complete?
Sooo ... the way I overcame this in order to make another similar mod work was to copy the Art and Text folders in "Civilization 3 Game Data" and all their contents into the top level "Civ III Complete" folder. Then the mod can find that layer of folders and files. You could get over this immediate problem just by creating an empty folder called "Art" containing an empty folder called "Units", but it may fail again later if the folders are empty.
That gets you past stages 1, 2 and 3 above. After executing those two steps the software is back where it started, at your "Civ III Complete" directory. Step 4 then requires it to find a "Civ3PTW" folder. There isn't one. The Mac version of this is "Play the World Game Data", and that does contain the rest of the folder path specified. So to make that bit work without breaking anything else, I suggest you make a copy of "Play the World Game Data", in the same "Civ III Complete" directory, and rename the copy "Civ3PTW".
After this it *might* work
