Ok edit, I got my msn working, though its like a classic version and the skin is like old, I wanted the new msn thing that has a newer skin and all that
Mehh? Try going to add/remove programs, if it's there, remove it, than you'll be able to do it again. If it's not... iduunnnooooo.
Just do a system restore and you should have your problem solved. Here are links on system restoring in Vista and XP
Thanks onlygfx, I system restored and now everything is back to normal, but does anyone know where to get a halo theme for MSN?
Download this, http://www.msgpluslive.net/ , install it then you can look for a skin you like here, http://www.msgpluslive.net/skins/ I did a search for you and couldn't find any halo skins :/
