My Open API Keys Were not Converted

So after troubleshooting errors on app I work on I discovered that there were big changes to the way the open API is being handled. I didn't get the notification message about the change, so this is all quite a surprise to me. It would appear that my account was not converted. What do I need to do if my account was not automatically converted to the Free plan when the change took place? When I login and look at my current keys, it says I am not a part of any plan. If I add a plan, will my old keys show-up? Or is there something else I need to do?
