Do you have items in you queue?
If you do, then the currently queued items wil still download slowly. Any new content, will download at the higher speed.
You can reset your account and password in Content Manger.
Go into your account setup screen, and renter your username and password. This will force the Planet Auran server to update your account information, and you should be all set.
Personally I've never waited more than a day for the account to be active.
