I've studied logs and dumps from the reports you've sent. And I haven't seen that your wallet has the key for the address
1GtBwpyUbSFjqyZpRtUuvtQHrC5EHAPtxx.
I see you've sent your coins to that address, proof:

https://blockchain.info/address/1GtBwpyUbSFjqyZpRtUuvtQHrC5EHAPtxxMay it be that you copy-pasted the address from the wrong place? It seems like this address belongs to an exchange in bitcoin universe (some exchange has the key to this BTC address). To confirm this you have to look for BTC deposit address on the exchanges you're using. The chances are you'll find it there.
Thanks for your time and patience.
That's a lot of detective work. Perhaps the exchange is BitBank?
