Problem running Limewire

[alchirico]

I've been using LW for a long time now and never had a problem running it before. Today, when I tried running LW, I got the attached error msg. I reinstalled LW from my DL directory and still got the same error. I then uninstalled LW and re-DL'ed it from the Limewire website, installed it and got the same error. I don't know what is going on, but prior to this problem surfacing, I'd got a message to update Java, which I did. I believe that LW uses Java so that may be the problem. This is the detailed error msg:

I was directed to go to the Limewire website and click on Support. However, I am using the free version and it appears that Support is only available when you purchase the Pro version. Can anyone assist me with this. Otherwise, I will have to switch to another p2p service.
