It's Just at school. At home, with my wired connection, Messenger Plus works perfectly fine. But at school, Messenger Plus dces me from the group chat, and possibly the rest of the people too. Reinstalling Messenger Plus has not solved the matter. Does anyone have a solution?

I think you may have got mixed up. You sound like you're having a problem with group conversations in Windows Live Messenger, which is unrelated to the Messenger Plus! Live add-on. Would that be correct?

Nope, Because without Messenger Plus the group chats work properly.

Doesn't seem like they're related. Messenger Plus! Live shouldn't affect group chats.

Even so, without Messenger Plus i can do group chats.

Messenger Plus does not interact with the WLM protocol meaning it has no effect on it's abilities to perform certain functions. Are you able to file transfer (with or without plus)? I think it's probably more connected to p2p connections and your school blocking those...

Hmm. Idk about file transfer, maybe i'll try tomorrow. But what's funny is that, i see my classmates having group conversations. O_O

Omg, now even my desktop has this problem. Someone help.

I can't believe you school willingly gives you access to install stuff on the network

It does. But my laptop's Messenger Plus still isnt working properly. So sad...

Have you tried removing both WLM + Plus!, restarting, then downloading and installing again?

Have you tried Add/Remove Programs > Messenger Plus! > Repair Messenger?

What security programs do you have? Something may be conflicting. See here.

Do you have any other add-ons for WLM? e.g. SweetIM, Smiley Central, etc. See here.
