Doesn't look good. If it were me, I'd remove LW using your Add/Remove control panel. Delete my LW preferences folder called
.limewire & found here:
C:/Documents And Settings/your_username/.limewire
I'd check my computer over to be sure there's no problems with it using 'all' types of utilities (maintenance & anti-virus, etc.)
I'd install Java:
Java 1.4.2 (click on link)
And re-install LW:

(Else you could try using the Repair function in your control panel.)
