K, I've Unpacked the files, and I've copied the #ROMAN_PAVED_ROADS.TGA files to the C:\Program Files\Activision\Rome - Total War\Data\packs\DATA\UI\BARBARIAN\BUILDINGS and C:\Program Files\Activision\Rome - Total War\Data\packs\DATA\UI\BARBARIAN\BUILDINGS\CONSTRUCTION folders.

I've even made renamed copies for good measure. No dice, the paved road icons remain the default barracks.

Anyone have any information that could aid my mission?
