The McNeel page that send you a licence number
upon entering ones email address has sent me my Licence number but a landscaping free prog for Rhino (Twinmotion) says its invalid and denies me the download.
How can I double check my Licence number ?
If that site has a database it checks it against, how do I resolve this problem as they have an apparent zero support/help link (as is the modern way of life !) ?
