ok, hi welcome to the forums...
now you convinced me into making it (finally) available to the users.. go here :
http://amsn.svn.sourceforge.net/viewvc/amsn/trunk/amsn-extras/plugins/emoticons_importer.tar.gz?view=tarDownload the plugin and install it into aMSN, then go to the plugin selector, enable the plugin, browse to the directory where you extracted that emoticon pack (it must be extracted into a directory), then click "Import Smileys".. after a while, they should all be in there.
Hope you're happy!
