Buying Pro entitles you to free updates & email support for 6 months... providing you bought Pro less than 6 months ago from the official site www.limewire.com your email address should still be valid.

You would've recieved a link to your Pro personal download page when you bought Pro!

If by some chance you bought from a scam site & not the official site, your email address would never have been in the database.

If you do have an official version that hasn't expired, send a PM to limenathan...you'll find a link in the thread below
