You used 1B49qTqGUm6ukgNhzv7YNEdnj3h5k4JKoj instead of 1B49qTqGUm6ukgNhZv7YNEdnj3h5k4JKoj when connected for the first time and this is how your username was created. This was an invalid BTC address so payouts weren't made. I just renamed it and you should expect payout today.
This seems to happen a lot. Maybe the "Start" instructions should indicate that BTC addresses are case sensitive.
People should just copy and paste their BTC addresses anyway. Since they're complex and associated with money I don't know why anyone would try to type them by hand.
Why not have the pool validate addresses when a miner connects, and refuse connection to invalid addresses?
That way someone would know immediately that there was a problem, rather than finding out days later, and the pool op having to make manual fixes?
