It's a really nice mod with a negative caveat. You can't use it right away, need to email them a request for license at which time they send you the seed and key. It was easier to remove the single line requiring the key than waiting, what is now well past the 12-24 hour response time to get the key. Maybe they're on vacation.
Thanks for the feedback but we usually respond in that window. We will try to automate the licensing system in the new version. Thanks,Armaan.
