Activation code invalid

I recently purchased typesy and have set up three user accounts so far.
When I tried to set up number four this morning the activation code keeps on coming up as invalid?

Thank you for contacting us.

I sent an email. Please check.

If this still doesn’t work, let me know the name and email address of the user you’d like to add and I will replicate the issue on my end.

Hi. I am having the same problem. I have purchased Typesy a while ago and have had only one user: me. Não I am trying to create a profile to my son and it says that the activation code is no longer valid. Can you help me?

Thanks for your attention.
