Done a System Restore
 

I subscribed to Limewire a year ago and paid $50 for a 2 year subscription, and today i done a system restore and lost everything, I seem to not be able to find anywhere that i can dowload the Limewire again without paying for my subscription.

Sorry to tell you but you paid a scam site for your limewire as there has never been a 2 yr subscription, they have only just introduced the 1 yr subscription..
This is the official site for Purchasing Limewire Pro, Limewire basic is free..;)

Lime Wire » Download LimeWire

But why was i using lime till just fine till now

Because they give you the official Limewire and make you pay more money than it's worth..As I said Limewire Basic is free...
Try contacting the site you got scammed from and ask them why...

well....you were using LW fine until you did a system restore and obviously your restore point was before you installed LW....or do you mean you reinstalled windows?...either way, you've lost the installer and now are faced with the issue of either using the free basic version or paying for the pro version...
