Limewire disappears on first load everytime

[WebAsh]

Whenever I start Limewire for the first time that session (ie, after I've turned my computer on) it will load all fine, display the whole interface and even show the "upgrade to pro" nag thing, but then it will just disappear. The window will close, the icon in the system tray stays but only until I mouse over it and then it disappears too, and then I have to load it up again. Why does it do this and is there anyway to fix it? My Java is fully up to date and so is limewire. But that doesn't seem to matter anyway as I have had this problem for a long time. (been through many updates of both java and limewire and still the problem persists)
