Unable to Join a Meeting

[Michelle15]

This has probably been asked before but I'm trying to click a link to join a meeting which isn't working. It opens my Desktop App but I'm asked to Sign in. So I did and go back and click the link and nothing happens.

I figured I should manually input the Meeting ID and Passcode once I'm logged in but the Join a Meeting button is grayed out. When I look around the web for help I find that this can be grayed out before signing in so they recommend signing in and then click the Join a meeting button. However I am already signed in and the button is still grayed out.

Not sure how to join this meeting.

Please check out the attached image

How can I get connected to this (and maybe future) meetings?
