So sorry that you could not join us last evening. I am not sure what caused your problem and as you say you clicked the link you must have received the email with the details of how to join. Several members did not receive that email because they had not informed the society of a change of email address or it was in their spam folder.
Have you signed up for Zoom? It is quite free and can be found on https://zoom.us/signup
Did you try copying and pasting the link into your Address Bar?
