This is probably the second time I've done this when trying to actually help it. So if anybody's good with computers, continue reading.
I tried deleting Msn Messenger 5.0 because it would always interfer with my other Msn. So I went to Control Panel, Add or Remove Programs, and then Add/Remove Windows Components. It sounded right, so I clicked on Msn Messenger (not any other ones) and pressed Next. Then I restarrted my computer, came back on only to see that everything in that list would not work at all except Msn 5.0. So I pretty much deleted everything instead of deleting the one thing I needed to. Now, I'd like to try the opposite, but I think I'd screw it up. Please help if you know what to do...
