I have a recurring meeting set up in my calendar. I was the originator
of the meeting. Now, however, if I open one of the instances of the
meeting, it says 'Organizer: my name' and the subject, location, etc.
And it's got up in the top corner 'Accept', 'Decline', etc. - as if it
was a meeting that was sent to me. So, when I need to change one
instance of the meeting, it will only change it on my calendar, and
will not send an update to all of the attendees.

How can I change this to make it an active meeting that I've created
again?
