erm ... sorry to tell you but unfortunately it sounds like you purchased from a 'scam' site, who then gave you a link to the free version of LW. There is no such thing as 'LifeTime or Unlimited' ... only scam sites advertise those things. O.o Sorry to say. It is probably a little long ago now to get your money back.

I can assure you had you really purchased Pro, you'd have been getting emails to inform you your support was nearing an end. And your LW would be telling you there's an update out, yours probably says upgrade to pro as well as to update your version.

Download the free version, it's not much different.
