You can still use the LW you purchased. What's happened to it? Like any softw program, if you want a new version you need to pay for it. You had the option of getting free updates for 6 mths. And of saving the installer to your comp to make backup of it. You can still use your older version or try out the free version of the new version or purchase pro again. LW does not have anything like a lifetime membership. (Only scam sites offer that & you only end up with the free version anyway. lol)

eg: you buy a car, 2 yrs later you want the newer version, do you think they'll give it to you for free.
