i d/l limewire a few weeks ago and everything seemed to be going fine until recently, when i opened it, it was not letting me see any of the program. Like I would click to open it and then it would just dissapear.....but it was still running. In other words, I can't see anything that I am doing if i were to try and play songs or d/l songs.

Are you sure it just isn't running in the system tray? If it is look on the right side of the start menu for Limewire's icon and right click it
