For anyone who still using TriLib 1.9.0 and needs access to the project and native source-code, please e-mail me using the contact form with a message containing your GitHub username and your TriLib invoice number.
I have set-up GitHub repository with the TriLib 1.9.0 Unity project and another one with the native libraries source which is compatible with the Unity project.
Users who already have access to the native libraries repository have been automatically invited to the Unity project repository.
