My brother in law asked what program can he download stuff for free. And I told him frostwire and limewire. I gave him my burned copy of limewire pro to barrow. But he said he tried to download a program. And when he downloads something he said it frostiwre and limewire say '' LimeWire can not open this file for security reasons.''. He told me this over the phone. What does this mean and how can I fix this problem? Thanks
