Hi, my 1st post, so be Kind!

I have been using limwire for a long while and have been using limewire pro without too many problems. I downloaded LW 4.4.4
Pro and when i try to start it up i get a java.lang.ExceptionInInitializerError

System is xp professional
pc is amd 2.8ghz 512mb ram
hd is 30 gb
java is Version 1.5.0 (build 1.5.0_01-b08)
This has happened with previous dowloads of LW pro, but it still worked, this time, nothing!

Any help would be appreciated, but keep it simple, I'm a newbie
when it comes to programming etc
