Can't install Limewire

I can't install Limewire. This is a recurring problem for Mac users, but there seems to be no easy solution. After downloading 2.0 (11MB version) with Stuffit Expander, UnStuffit opens an Install icon on my desktop, as well as a LimewireMac.bin file. When I click on the Install icon, a message says it's extracting the installer, then nothing happens. However, it places MRJ Installer folders and files in my trash with a (deleted) next to the folder name. When I click on the LimewireMac.bin file, Unstuffit opens another Install icon called Install1. When I click on the Install1 icon, it does the samething as before, putting more files and folders in my trash. WHAT CAN I DO??? I've installed the most recent version of MRJ Installer 2.2.5, and I've tried increasing the memory of the Install icon before clicking on it. I would love to have Limewire back, any help would be very appreciated!!
