If you do not see the addons ingame in the addons manager read this here to find your correct addons folder:

It's in the same forum you have posted, just as sticky postsa at the top. Always have a look there first please, it helps.
Try the "take screenshot" hint ingame to find the correct folder.
If this does not help then you need to tell us more details please:
Are the addons totally missing ingame in the addon manager AT THE CHARACTER selection screen.
Or are they in the list but tell you something is missing? Expand them then and check the dependencies, which can also be read here how to do:
