When you purchase pro they send you an email with a link to your own personal downld page. You should bookmark this page in future. As a pro user you're able to keep downlding LW updates for up to 6 mths after you purchase. If you don't wish to continue with pro payment after 6 mths then you should downld the program & save the installer to your computer & back it up onto an external device before your LW pro period finishes.

Use your original email address to find your personal downld page here: http://www.limewire.com/english/cont...pro_lookup.jsp

If you can't access it then either you've tried an incorrect email or send an email to LW pro support here: service@limewire.com
