hello there.
firstly its no problem
secondly i probably hadnt made it cler enough oblameme instead.
if your are in the correct folder for the mod
C:\Program Files\Steam\SteamApps\common\empire total war\data\campaigns\DMUC_Umain
-then there should be a file called startpos.esf.
-simply copy and paste this somewhere (anywhere it doesnt matter, just as long as you can find it if the want Dmuc back how it was before)
-once this is done, copy and paste the file startpos.esf from my downloaded file into thesame folder as before. it should say "do you want too replace this file", clickyes. and Hurrah, it is done, nice and easy
hope this helps
