If you still can't find it, just click Start - then Run and type in msmsgs.exe then press enter. That will bring it right back up.
I find the program but it wont load up.. And i use windows vista so i have no idea where the "run" function is :angry: *kicks vista*
Don't get me started on Vista. I HATE it. I download a patch and the stupid thing uninstalls my sound card... Grr! So after flipping out I finally figured out how to fix it. I did the same thing with closing the MSN window. I clicked on the start button(round button with red,blue,yellow,green flag.) Then there is a search thing and i put in Windows Live messenger... thats what worked for me.
