i have the same problem as the last guy, but you never answered, it how do i reload pro without paying again

I got the message that I had an internal problem, I copied the error and sent it to bugs at limewire, three times and never got a response. I un-installed lime wire and went to the site to re-install, I paid for the Lime Wire Pro the first time and do not want to pay for it again. What do I do??
