"MSN Content Plus" IS NOT "Messenger Plus!".
They are both completely different softwares.
The only official sites of Messenger Plus! are
http://old.msgplus.net/ and
http://www.msgpluslive.net/ (and their local versions).
If you want to download Messenger Plus! always use the official sites and not any other site.
This also shows that it is important that you call software by its complete, full and correct name.
