Do you use any other Steem based apps? Keys should work everywhere, unless there is a bug or if you're not yet approved for the limited beta.
If you're talking about the current busy.org, it only requires the private posting key as far as I know. The new site requires the private active key.
I've tried them all. This happened before. I had to do a recovery on my account and the same thing happened before the recovery and after. Maybe they just don't like me!
