Path must be wrong at some point.
Did you change it in Resource\Theme\Civ4.thm?

that is what I have in the misc file... I am pretty sure that is what it said to put.
I have checked and double checked the path names against what the tutorial says, and I can't see any issue, they are not in the My documents either, which i think was one solution to this problem...
WELL DONE that fixed it, I think it might be written wrong in the tutorial?
OH Wait hang on all my boxes have gone poof!! there are no menu boxes! what did I break this time!

if it weren't for all the missing buttons this would look pretty cool haha!
Ok fixed it... had to move the vanilla resource files into my mod
