Forget it! The same thing happen to me, I have a MAC OS 9.1 and I was using Limewire for a long time , but at the end it was running a little slow, that's when I decided to buy and download the new version on Limewire(it was suppose to run better) I was able to downloaded successfully but it wont start,so I went back and downloaded the old free version of limewire and it won't work either, I emailed the support guys and the solution that the gave me is that I need it to upgrade my computer to an OSX....!
