im a bit confused. Ive had Messenger Plus! for a while now, but recently ive noticed that if i try to use the activities, most of them dont work. When i try it, it says i need the latest version of msn and gives me a link to the microsoft site where i can download it. Ive downloaded it countless times though, but it never works, and it just keeps telling me to get the latest version. Is my Messenger Plus! stopping me from useing the activities?

Can you give us the result of typing (!VER) in a conversation window?
This will give you 3 versions: those of Windows, WLM and Plus itself.
Post that here, and then we'll see whats going on.
