So, another noob question.

I began PODC mining a few days ago, staking the 1000 BBP given by the faucet.
My first two payments were 10 BBP each with 10% rewards.
Now, after a few days of running the BOINC  manager 24/7, I haven't been paid since.
If I run exec totalrac in the wallet console I get this message:

"Total RAC": 2284.15,
  "UTXO Target": 50251.3,
  "StakeBalance": 0,
  "Note": "You have less stake balance available than needed for the PODC UTXO Target.  Coins must be more than 5 confirmations deep to count.  See coin control.",
  "Threshhold to receive 10% rewards (below this UTXO Amount rewards are lost)": 1827.32,

So, what do I do now? Do I have to buy BBP from an exchange to continue mining? Or stop the Boink manager so that my RAC drops?
