Thanks for the reply...
But the major problem is that I didn't even get the confirmation e-mail from LimeWire and I live in Taiwan so I wasn't able to call anyone!

I wrote several e-mails to both LimeWire and Paypal but neither of them bothers to reply!

I did what most of the users recommended "Purchase only through www.limewire.com" and still I got scammed?!

Can't believe this....@@
