The miner probably is working; the problem would be that the hashrate is so low that it rarely submits any shares, so we can't calculate a hashrate. We haven't really optimized the statistics to work well with very small miners, but there's no reason they shouldn't earn money. Look in the share history and confirm if any shares were submitted. If you leave the miner on automatic difficulty, eventually the share difficulty will drop to 32 after the mining server determines that the miner doesn't submit shares frequently, but for a miner that small, it may take multiple hours for that to occur.
