The installation seemed to go fine, but when I try to start limewire up, I get this error message:
"Fatal Application Error, Invocation of this Java Application has caused an InvocationTargetException. This application will now exit. (LAX)"

I can also view the details of the error, here they are:

What does all this mean? I believe I have the current version of MRJ (2.2.5)
What is MRJ? How does it affect limewire?
I would appreciate some help with this as I do not know what to do.
Thanks alot

I have the same problem!!!
I have tried doubling the memory allocation to Limewire to no avail. i have also reloaded limewire twice (no easy task on a 32k modem connection)
HELPPPP!

I'm having the same problem, except for the error details (see below). Any help would be appreciated.

I don't really know what the problem is but I can tell you what MRJ is.
MRJ means MacOs Runtime for Java, you need this to run Limeware becaus LW is an app constructed with the Java programming language. This also why LW is a cross-platform app, Java can be read on a PC as well as on a Mac.

I had the same problem when I first installed LW. When you download LW it checks if you have the correct MRJ running on your Mac. If you do'nt LW will download this first before it will download the actual app itself. Maybe this is where it's gone wrong. What helped for me whas that I downloaded the latest MRJ from the official Apple website first and then downloaded LW.
NOW IT WORKS PERFECTLY!!!

Sorry for the spelling I don't usualy speak english.

Actually I do have MRJ 2.2.5 (the latest version as far as I know) installed, so this is not the problem.

Me 3!suddenly when i click on limewire i get this fatal app. error message!Invocation of this java app. has caused an exceptional initializer error-this app. will now exit. ????what gives?did i delete something downloading some other apps. or what

I get a fatal application error as well...i was hoping for some help here but...anyway as soon as i get some answers i'll post them-jpf

Hey, I am a brand new to LimeWire. In fact just today I went to apple and downloaded the MRJ 2.2.5.smi and installed it. I restarted my mac (running OS 9.1) and then went and downloaded LimeWire 1.7. I installed it and restarted the mac again. When I tried to use the software I got the same problem that is being reported here. Here are the details of the error message:

Any ideas on how to fix this?
