That's quite a different java error code. Haven't seen one quite like that before. And I'm only basic at reading them.

I've a suspicion that if you follow Peerless's advice, it might solve more than one problem.

I suspect the Java issue is possibly also security related.

Is Vuse running ok?

Lord of the Rings : No, Vuze doesn't work too. I have the same problem on both LW and Vuze.

Peerless : I use CCleaner to clean registry. May be you are right, I have to reformat (what a pity).

Thanks

Probably is a Java issue. Limewire will not run if your Java is not the correct one for your operating system or if it somehow got corrupted. My computer for years could not DeFrag either and I spoke to a number of Dell Tech people who had no clue why not. I've wiped clean my hard drive and put all the crap back but that didn't even fix it. I'm running an old version of LimeWire and it is simple and very fast, version 4.8.1. If you can find a copy worth downloading it.
