Save your money. Not a much functionality and author seems to have gone MIA. Message on support forum from August 2017 still unanswered.

Super pleased with this product. It has allowed me to change phrasing for the smaller airports, so that instead of 06C, FSX will now say "Schaumburg", etc. Also though the community feature, it adds a bunch of new airport and airline call signs. Yes, there is a freeware version, but why?
