Registration closed - how can I re-open it

I set up registration for a meeting - the account is capped at 100 max per meeting.  The registration filled up fast to 100 so I purchased the the 1,000 large meeting package from Zoom - but the registration link still says that "Registration is closed"....

Any ideas on how to re-open registration?  Or will I have to set up a completely new meeting and registration process?
