After the last zoom update, my zoom audio has stopped working. When starting a meeting, it says "this meeting does not support dial in or call me to join. Cannot join audio."

I have never needed to use dial in before. The "test speakers and mic" shows both as working fine. The audio will not give me any option to connect through my laptop's sound.

For the past 3 weeks, we have gotten an emails "A meeting in your account has been running for 8 hour(s)".  

This meeting is started in the early morning (like 1 AM) and is started using the account for one of our Zoom Rooms.  The zoom room does have the whole logitech device hooked up to it.  

There is no one in the office at that time to start a meeting.  The meeting does not show up in any of the logs.

Has anyone had this happen?  or any idea what the cause is?

I have a meeting set up requiring registration that I sent out 25 invitation emails with registration links.  16 participants have been able to register so far.  Several others have not been able to register.  The error message they get is "This meeting is for authorized registrants only. Please enter another email address. Sign up free."  The email address they are trying to sign up with is the same email for their Zoom account and they are logged in to Zoom.  There are multiple domains for the email addresses having a problem (comcast.net and hotmail.com).  I have asked them to try different browsers and different email accounts, with no success.  Does anyone have any ideas of what else I or they can try?

Thanks,
