Limewire wont run
 

Ok, i have a huge problem. when i start up limewire the little square in middle comes up and then goes white. It loads it just fine and everything but when limewire comes up it also is white. If i close and reopen the window it apears but it freezes up. I have a new computer(3,0ghz 512mb Ram) with fully up to date sun java. If you guys could help me out i would greatly apreciate it.
