Set your FTP program to merge the directories.

You must be doing something wrong copying the files over.
You have to click overwrite if asked.

Also, don't forget that addons must be copied into the /library folder.

Feel free to read the Official XenForo Manual on how to Install addons: http://xenforo.com/help/add-ons/

You should upload the add on files inside the root of your forum folder preserving the structure intact.

It looks like the dark_taigachat table already exists at your database. Try to delete it and give the installer another go.
