HOWEVER, since you're using MT-Newswatcher, you should just be able to
choose Edit/Show Details, where in the headers you'll see something like

Which is a list of links to all the messages in this thread. Those links
should be live: CMD-click on one of them and you can retrieve any of the
previous messages in the thread, as long as they're still on your news
server (and if they're not, you can always connect to the
news.microsoft.com server directly - Special/News Servers.../New -
generally the messages stick around for a couple of months).
