If downloaded correctly there should be 2 icons on your desktop. One will say Limewire with the green icon and the version the other will just say lime wire. Go to "My Computer" and check on C drive if this is your main hard drive then double click on Program Files-Limewire should be in there like this: "C:\Program Files\LimeWire\LimeWire.exe" if it is not there then or course you will have to download again. Contact me on Yahoo messenger as user misty_blue_seas and we can IM and see what happens. The 2nd icon on your desktop should just be the shortcut, but if both are not there then will download again. Are you using the free download version? There is also Itunes but they charge 99 cents a song I believe. Let me know
