If you are using windows Vista, you have to unpack the .zip or .rar of the mod onto your desktop, then unpack/unzip all other mod-mods to your desktop also, then, when you have the mod with all the modmods you want, you then cut and past the whole mod folder to your mod folder for the game: C:/programfiles/firaxis games/.../BTS/mods.
Also, for Vista, once you have the mod up and running, and you want to change the contents of one of the XML files for example or add a modmod later, then you have to unpack/unzip the modmod to your desktop then copy and past all of the files into your mod folder as above.
Finally, I recommend (for changes to individual files) to save a copy of the file on your desktop, change the internal contents, then cut and paste the file back to where it came from.
If you do not do the above, then changes are not saved in Vista to files saved under the C:/programfiles/... directory.
This has been my problem in the past, and it may be part of your problem now, os79. If not, it's good advice for all other Vista users.
@jooyo, I still can't get browninterface to work, but that's a minor thing really
