I have recently installed and updated to version 4.12.11 and when I click on the LimeWire icon to load the program, the program begins to load but never starts. I just get stuck on the little green box screen with the LimeWire logo. I have also tried to install the new 4.13 beta version as well, but the same thing happens. I had 4.12.6 installed and it worked fine, but now when I restore my computer to a previous time, LimeWire doesn't work anymore. Please help.
