[BTS] Music Modding/Crashing Fun Times! (errors)

[Squablo]

I tried adding some songs specifically for the future era, adding the songs into their own directory (yes the directory in the XML files does exist in my files) and when I opened Civ 4 up it crashed after the intro videos.

The audio log had a lot of this in it:
"

[229005.844] ERR: FAudioManager::GetAudioTagIndex(): Could not find string AS2D_ANCIENT_SOUNDTRACK_2 of TagId 3

"
etc, you get the point. It did this with every single AS2D tag there was, including the ones I had just added.

I attached the XML files below. The songs are added to the end of the section. Search for "Anthem" and you should be able to find them. Any idea where I went wrong?
