I have 2 issues here. First is that the license listed in the validation license key box was different than the one sent in the email, but when I validated online, it worked anyway.
Then, for my offline computer, I went to the address mentioned in the validate from another computer box (https://mcneel.com/validate/rhino/mac/5) and got a blank page so I can’t seem to validate that one. Would like to validate offline if I can.
