Zoom video is not launching

Hi:

Zoom seems to have done a recent Update - I noticed my icon changed - but ever since then the video won't launch! Everything looked normal - put in my id and password & then it asked me whether I wanted everyone to see my video etc and I said ok but then nothing. I see the mouse flickering a few seconds and then nothing - the final step is not being completed - I can't get video!

Has anyone gone thru this?
