First, I am new. I just downloaded and installed the free version of LimeWire.
When I click on the Get Information to determine what version of LimeWire I have, I get the following information:

LaunchAnywhere 4.5, Macintosh Edition, @2001 Zero G Software. Inc.

So what gives? What version of the free LimeWire is the current latest version and how and where would I get it. The version I have is limited in features but apparently works. I have downloaded one audio file, a song, and it works. It is not a great copy.. even though it showed 4 stars. Any advice and suggestions will be appreciated. Should I buy the pro version of LimeWire? Thanks in advance.
