Roborun 1.8 License Purchase

I just upgraded to Roborun 1.8, and when trying to upload a microbasic program to my controller an error box pops up (see attached image) stating that I need a license.



I have no issue buying the license, the microbasic scripting is very useful, but I can't find where to purchase the license on the website. Can anyone point me in the right direction?

Thanks,
Phil

how we get the license
