I went back to Limewire 1.8c Mac and realized that it crashes too. However, I can keep it running virtually forever if I do not access any of the menus at the top of the screen (Apple, File, Help, etc.). It's kind of annoying but worth it. Also, Limewire 1.8c seems to allow access to FAR more files than 2.0. I wonder why the heck that is. LOL. Aren't upgrades supposed to be better? I have 2.0 on the PC laptop and 1.8c on the Mac and I get far more files on 1.8c.
