HELP--keeps quitting
 

Hi,
I just re-initialized my drive (bad memory problem now rectified) and had to reinstall all my apps. I decided to try LimeWire 2.63 and had the same problem everyone else has been having--non-fatal errors, then type 3 crash.
I went back to my saved 2.55 but now when I launch I get this message:

This Application has Unexpectedly Quit

Invocation of this Java Application has caused an InvocationTargetException. This application will now exit. (LAX)

Any help/suggestions on how to rectify this?
BTW, I'm on a g3 OS 9.2.2 powerbook and dragged my old MRJ folder back into my new sys folder.
Thanks
