Off line for 5 days..Project will not render

Our whole neighborhood is offline for 5 days due to construction. I cannot render because my computer of course will not connect to the corona license. Is there any other option so that I can finish the project? I wrote support, and they told me they would get back to me in a day or two …so far no answer.

You can temporarily borrow a license for offline use as described here: Chaos Licensing
