Have problem with license after purchase

macOS Version: 10.14.5 (18F132)
Description of what you need help with:
Yesterday we purchased an annual license with a link to the following this email: bespalow@miura.tech - however, after installing the Principle and entering the key sent to the e-mail, you receive a notification about the unlicensed license: http://prntscr.com/oq10sp -could you tell me what to do in this case?
Thanks

Steps to reproduce the behavior:

  1. Paid license
  2. Downloaded the distribution from the official site
  3. Install Principle
  4. Enter license key

I just rejiggered some stuff on my end. try again. if you still get the message, the license key you’re entering may have a typo. you can look up the license key here: http://principleformac.com/account.html
