It's probably the "double folder" problem.
In your BtS\Mods\American Mod Revolutions v.5 folder there should be a folder "Assets", an .ini file, and probably some more stuff. Then the installation is correct.
But it sounds like if there's another American Mod Revolutions v.5 in the first American Mod Revolutions v.5 folder. Please check it, is that right? If yes, then move everything from the second folder in the first folder, and check again if it works.
