I had similar issue when trying to get into my community account I created. I then added my community account name to keychain, clicked the import keys, and then all was fine. A simple solution if it works for you. I only ever got that one account password, so try just adding your hive number name to keychain and give it a shot.
I tried various combinations of the keys I could find, but somehow I must have messed up. Another one I made is fine. It's not a big deal as this community is small and now very active.
It could be all different over the weekend with the hive.io coming on friday. I'm kind of looking forward to it, a new fresh start.
