I just had this problem on my imac snow leopard, and spent many hours trying to stop lime wire from starting up at login I tried every thing the tec support people told me to do but nothing would stop it. then a tec person from Brisbane told Me to put the put COOKIES AND CACHES INTO THE TRASH, AND SECURE EMPTY TRASH, and this fixed it straight away and solved the problem. am so happy,hope this helps you.
