Alright,  I was trying to join a group chat on computers on yahoo but they applet never loaded.  It said that I needed an updated version of Microsoft MV to load it.  But, I don't even have Microsoft MV and I have been able to talk on chats forever until now.  And I was going to download it but it said: "Once installed, you can't delete it."  So I don't know what I should do.  I would appreciate your help.
