How do you...
 

I downloaded the Edit and now it is stuck saying it is still playing, now I can't use LimeWire at all. The silence is disturbing me

Quit the app then relaunch it.
If you can't quit then Force quit.
Remember not to overburden a slow computer by keeping too many windows open, especially if you don't use some of them, 'cause they still take RAM.
Post again if this persists.
