I've been trying to link my Spiral Knights accounts to my Steam account, except I keep getting a message that says that the account name could not be found, when in fact, both my Spiral Knights and Steam account both have the exact same user name.

Is there a technical fix towards this, or do I have to first download the game through Steam and then register to make it work? Note, I've been playing Spiral Knights for a bit already and downloaded the client from the main webpage, and now want to link the account to my steam account so I can access the in-game voice chat system.
