Also, you replied to another users post instead of creating your own post. So 2 things here.
1. Whenever you have an issue, please create a post specific for that issue instead of replying to another post about a different issue.
2. You posted your license key for the world to see. Also, and the author of the original post you replied to got an email with your license key too because you replied to someone else’s topic.
Please create a new post for you issue. I don’t think the issue is you license key. I think you are probably trying to activate an older versions. However, since you posted your license key to the world, I now have to cancel that key and issue you a new key. Anyway, I will follow up with you after you make a new post topic.
