The answer is yes. You get 6 months of free updates & customer support. Even after that time you can still continue using the version you have. There's no dramatic differences, except connection quality for LW should generally remain at turbo charged so you should get reliable results.

By the way, if you purchase it, there can be anywhere up to a 24 hour waiting period before you receive an email from customer support with a link to your personal downld page.
