help me please !!! sorry my english is not good.

There's something strange about your wallet.
When I look up the payment address on the Block Explorer the transaction isn't there ->
http://cloak.blockexplorer.cc/address/BxTmSYLcQ6Fx6rscppLYVcbX7okT59tLfuWhen I trace the other payments to this address I don't see the mining you're showing in your wallet screenshot->
