No, no more updates, from me atleast.
I don't have the files at this pc, so I can just give you advice:
Check these folders for that unit:
civ3\conquests\conquests\wwii pacific\art\units
civ3\conquests\scenarios\wwii europe\art\units
the .ini should be named exactly the same as the folder (so if the foldername is mg_btln, the file should be mg_btln.ini). The same with every error. If you don't have the file in either folder, extract them from the main files in the folder wwii europe\art\units into the same folder on your civ3\conquests\scenarios folder.
Remember to check what file civ3 is asking for. If it's asking for mg_btln.ini, the folder (and .ini) has to be named mg_btln.
I'll get back home in tuesday, so I'll be able to help more then. Oh yes, remember to have the latest patch installed!!!
