You have to realise, msn have given up on not letting leaks out, apparantly you can download it at download.microsoft.com somewhere. There new idea is to block none beta testers addresses from signing in! Unfortunately people have already figured ways around it.
Don't bother with the mess.be msnp13 to msnp12 downgrader, it's hidious (advert)! You'll have to find a better one yourselves..
