Same with me, nthing changed on my PC, java had updated itself to 6.0 or something, and it kept limewire working for about a week. I was on limewire in the morning, disconned, shut down pc and went out for some lunch, came back, went to turn limewire back on (this is only maybe 3 hours later) and it never loads up. The Limewire box appears in the middle of the screen and never loads up limewire.

I have tried the fixes for limewire (the deleting settings folders etc. which did work for me last time, but that was after i had updated limewire which caused it to break) and nothing, still won't load.

This makes me think it's maybe a problem with limewire server or something, i dunno, but im interested to find out and get it working again
