Relax. If your wallet is synced, unlocked and running, it'll stake.
Patience is all... think of how many others have inputs trying to stake, and the weight noted in the bottom right green icon bubble... even if you are within parameters to stake, your CPU still has to make a valid hash AND you are fighting with all the other valid inputs to do so... it is likely PoS will be sketchy for almost everyone until PoW is finished.
Just leave it open, unlocked and wait. Others in a backroom chat have already staked a few times... it will happen.
Also, go vote... I have already been told by the guys running Cryptsy that the boss man was asked about BTCD, so them adding it to the vote so quickly speaks volumes... they just want to gauge total interest...
