I'm using OSX 10.6.3 Snow Leopard on an iMac. What happens is that the program boots, the screen from which I normally would initiate a search appears , and then the Limewire window just shuts down and I get a message about it having crashed and to send a report to whoever receives such things.

The last time I used Limewire, which was before the most recent OSX update, Limewire ran just fine.
