Limewire 4.0.8 crashing/Internet connection failiure

[Alexandre]

Hello! I am using Limewire 4.0.8 Pro on a Mac G4 --Panther 10.3.5 with a cable connection. I've had a lot of problems with Limewire crashing my mac upon start up. I've tried many things including turning off Norton Firewall (and then later uninstalling it), and deleting a lot of the files in the Incomplete folder (where I had a lot of them) and nothing worked. I would loose internet connection (browser won't work when it's normally working before starting LW) a minute after starting LW and then my system would freeze. I finally removed the Incomplete folder out of the LW. I was able to get a good connection in LW and my system stopped crashing but sometimes I loose internet connection from Safari but LW would still be connected!! Safari never screws up when LW is not connected. Any solution to these problems? I still have the old Incomplete folder where I have a lot of almost-done-downloading files. Can I still use them in trying to complete the download?
I tried going to http://www.broadbandreports.com/stest and I am getting a decent connection (455/207).
Also, I couldn't find the TOOLS-OPTIONS in the application.
