Hi hobo, thanks for your response. i installed the original software then decided a few hurs later to upgrade and followed the instructions from my software upgrade pop up. It took me to the lime wire site where i purchased pro for $18.88 via paypal. i have the reciept number and have been trying all week to get a response from limewire but to no avail. I could be getting all of this wrong so could you tell me what version lime wire pro is? i have limewire version 4.9.23. I'm completely stuck and not sure what to do. I've been enjoying the lime wire programme and really want to upgrade to improve my download speed. Any suggestions would be a huge help. Thanks again.
