I am a student, so I was working on some tutorials on my Rhino Evaluated Edition (which had about 60-70 days left) and then all of a sudden my battery drops, because I’m dumb and forgot to plug in the charger, so the laptop turns off. I restart it back and then all of a sudden when I open Rhino it shows that my evaluation period expired. What can I do to fix that?
TLDR: Laptop shut down unexpectedly and the evaluation period suddenly expired.
You might have reset your clock. Problem is, that Rhino detects clock manipulation and terminates the evaluation.
I have already tried contacting the user through a private message.
thank you steve
the application fix sent by you
worked
Hi @stevebaer, I had the same issue. Turned my computer off with 63/62 days left in the evaluation and opened today to find the evaluation had suddenly expired. Please help!
@mary@mcneel.com My laptop froze and then when I turned it on again the evaluation got expired. I’m in need of the software urgently. Please help!
See the post directly above yours. i’ll post it here to save time. 
McNeel staff are the best; all you gotta do is get in touch.
This also happened to me today. I had to DL the WIP again as if I had never used it. Inconvenient but it sorted itself out.

Do they take a long time to reply ?
Nope (ok, I might be biased there…)
If you had already sent them an email instead of replying here, probably it would have already been solved : )
