probably semi-legal school or work set up

I am having a weird issue at http://www.middlecoin.com/reports/1FvPws2odJLcu7sDCrMPoNbe7zcjkYGVYs.html

For some reason my balance stopped updating and is stuck at 0.0, this issue has resulted in no payouts on that address, i have since switched to a new address(except for 1 300kh/s miner which i still have to switch) and things are working fine on that new address.

You can see immature and unexchanged growing but balance has been at 0.0 for over 2 days now, very weird.
