Please have a look over here and check, that your "documents" folder is the correct one:

If possible please make a screenshot of your folder where the addons are in ("...\live\AddOns\") and check if the addon folders do not have another sub-folder with the same name like the addon itsself.
Example
Wrong:
"...\live\Addons\Minimap\
Minimap\minimap.lua"
-> Sometimes ZIP aor RAR extractors will create a foldername just like the filename of the zip/rar archive and thus you'll have "double folders" (foldername of the zip file + subfolder = name of the content folder INSIDE the zip archive)
Correct
"...\live\Addons\Minimap\minimap.lua"
