Did you use the auto-installer?
I'd assume so seeing as that's all that's there... Lets see what's next?
"When prompted, chose your AoM directory. It should be C:\Program Files\Microsoft Games\Age of Mythology\"
Is that the correct directory?
Did you have any instances where t wanted to overwrite any files?
"TO PLAY YOU MUST USE THE "lta.exe" (NOT the normal aomx.exe). LOCATED IN C:\Program Files\Microsoft Games\Age of Mythology\"
You said you did that...
"You MUST copy and paste the "scenario" folder to your "My Documents\My Games\Age of Mythology\" directory in order to play the scenarios."
Did you do that? I missed that my first time...
"FotR_Mod_Install_Test.scx" is designed to test if you have installed the modpack correctly.
Did you try that?
"- Before running, make sure you do not have any of the following files. If you do, back them up first.
--data/protox.xml
--data/protox.xmb
--data/unittransform.xml
--data/unittransform.xmb
--sound/soundsets-xpack.xml
--sound/soundsets-xpack.xmb"
This is probbaly your mistake... Make sure you double or triple check this part.
