Verry important, i´m knew here, can anybody help me?
 

How can I play the downloaded games...? The games are in "library", but when i double-clicked on them a message came "lime wire will not launch the specified file for security reasons".

Please, can anybody help me, it´s so important and i´m knew!!!

You'll have to exit LimeWire and then go find the folder where you downloaded the software to and launch it from there.

You don't have to exit LimeWire. Just start your favourite teminal emulator, switch to the path of your Shared directory and enter:
./(name of the executable goes here)
