I Purchase Lime Wire On Line And I Can't Down Load This Product.

I'm sorry to say but you most likely have been scammed. The official Limewire has not been sold since 2010 because of a court order. I would dispute the payment with your credit card company.

I went to the Limewire official website at http://www.limewire.com/ and this is what I see. 

LIMEWIRE IS UNDER A COURT ORDER DATED OCTOBER 26, 2010 TO STOP DISTRIBUTING THE LIMEWIRE SOFTWARE. A COPY OF THE INJUNCTION CAN BE FOUND HERE. LIMEWIRE LLC, ITS DIRECTORS AND OFFICERS, ARE TAKING ALL STEPS TO COMPLY WITH THE INJUNCTION. WE HAVE VERY RECENTLY BECOME AWARE OF UNAUTHORIZED APPLICATIONS ON THE INTERNET PURPORTING TO USE THE LIMEWIRE NAME. WE DEMAND THAT ALL PERSONS USING THE LIMEWIRE SOFTWARE, NAME, OR TRADEMARK IN ORDER TO UPLOAD OR DOWNLOAD COPYRIGHTED WORKS IN ANY MANNER CEASE AND DESIST FROM DOING SO. WE FURTHER REMIND YOU THAT THE UNAUTHORIZED UPLOADING AND DOWNLOADING OF COPYRIGHTED WORKS IS ILLEGAL. IF YOU HAVE DOWNLOADED LIMEWIRE SOFTWARE IN THE PAST, FILES ON YOUR PERSONAL COMPUTERS CONTAINING PRIVATE OR SENSITIVE INFORMATION MAY HAVE BEEN INADVERTENTLY SHARED AND YOU SHOULD USE YOUR BEST EFFORTS TO REMOVE THE SOFTWARE FROM YOUR COMPUTERS.

Not sure if you just recently purchased Limewire but if so it wasn't the real Limewire. I would call your bank and have them stop payment, or dispute it through your bank.
