No, when you log onto your other computer go here: http://sales.limewire.com/support/pro_lookup.php and put in the e-mail you used to purchase LW and d/l it:).

Unless your past the 6 months, then you'll have to back it up onto a cd and transfer it that way or use a usb cable or something like that.
