It's not working simply becuase you forgot to correctly edit the description.lua file
it should be like this : countries = {"USA"}
but you omited the last part of ={"USA"}
I edit it and its' working now.
Check also the comments section on DCS website download page, as someone already made this comment but apparently you did not read it.
As someone suggested you should also change the installation description method : there is no needto place the folder in \bazar\liverries\uh1 , but just simply create a folder in \saved games\ Liveries\UH-1H and there you can copy the CIA BLACK HELICOPTER or any other skin.
Other than that the livrery is one of the best in DCS even tough its fictional, please REMOVE the CIA LOGO from the nose and this will be perfect.
Please also make a skin like the one in X-FILES and in the cases of ufo sigthings etc : MEANING all black :D ;)
