Can't download version 2.8
 

I've got limewire 2.7.3(which I obtained from download.com). I've tried to download version 2.8<macintosh> , I have OS 9.2 installed on my iMAC. When I try to download the installer for the mac off of limewire's site, I get a message about not being able to open the download because of missing octet-stream application. I've done a search for octet-stream applications for the macintosh and can not locate any!?! Any advice on how to successfully download version 2.8 for OS9.2?
