I have previously payed for the pro version of limewire, yet I can't find the installation file. How can I get the installation file back? ty

Did you lose it due to a crash or reformat?? If so then it depends on when you bought your Pro version. The suscription is only good for 6 mnths and just recently been offered for a year. So if its been longer than 6 mnths your e-mail address won't be in the data base any longer. If you want the updates and "e-mail support" that they offer, then you will have to re-purchase.
It's always a good idea to backup your Pro installer.
