Hmm, I have three problems using the EDU mod (installed 2.6, then 2.8. Running Civ IV vanilla 1.61):
1) When I start a game Civ IV complains about "Tag: UNIT_ARCHER_AFRICAN in Info class was incorrect. Current XML file is: Units/CIV4FormationInfos.xml" (The dialogue box has a title of "XML Error")
I have this same problem using Windows XP.
EDIT: I fixed it by deleting the UNIT_ARCHER_AFRICAN lines in the problem file.
