Thanks for the reply.
In working with the DA Toolset, all of the DAO vanilla base game content is available to access and change through the Toolset, but not any of the DLC (including Awakenings). I have found that if I try to open any of the DLC with the Toolset, it needs a password. I'm guessing they did that to keep people from offering their DLC as free mods or somesuch? Or maybe they just forgot to make it accessible? I don't really know their game plan there.
In any case, it does make it pretty tricky to work with modding the DLC. If anyone knows how to work with the DLC in the Toolset, I'd sure appreciate the solution.
