for some strange reason, everytime i try to do anything whether its listen to a song or downloading, it says that we have security something. security reasons. please help. i do not know what to do.

Please be more specific in your problem. What message, what exactly does it say, is it from LimeWire or your system/firewall, & after doing what does it give such a message?

The only security message I'm aware of is when you try to launch a non multimedia file from the Library window. Launch only applies to video & audio files, not programs or zips, etc. & thus shouldn't be used for such.
