Unfortunately you were scammed. There is no such thing as Lifetime membership for LW. That's what scam sites advertise. They make you think you are getting pro, then give you the free version. And two years ago LW Pro cost $18.88 for 6 months support.

Part of the problem is LW.org do not advertise. But scam sites sponsor advertisements in google, etc. So when people search LW in search engines like Google, the ads show up at the very top & sides of the search results, people see them & are attracted to them.
