LW/FW will not stay open (mac)
 

I installed Limewire on my mac (OSX 10.4.4) some time ago. I ran fine for a while, but after a week or two, it would shut down after remaining open for about 30 seconds. I uninstalled and reinstalled it. Once again, it ran fine for a few days, then would quit out unexpectedly after staying open for about 30 seconds. I downloaded and installed Frostwire, but I had the same problem, with the application closing on its own after staying open for a short time. Is there any way I can fix this problem?
