Java error after a crash

I've been using limewire for a long time but never get any problem. Today, after a accidental log out of the system while Limewire is still downloading something, I can't launch the app anymore. Just get this error message:

The main class "com.zerog.lax.LAX" could not be loaded.

The only button shown is "Quit"

Can anyone here give suggestions to me?

Thanks!!!

i even reinstalled mac os x and got that error.

i dunno what to do.
