I had 1BTC sent to my DT wallet, the 1BTC was never credited to my balance and is still sitting in an offline wallet. I confronted the owner of the game "Di" and all he had to say was "it looks like there MAY have been some bets placed around the time of the deposit, but I cannot look that far back into my database." I was never even credited for the deposit, so there is no possible way for me to have made bets with it. Below is the tx id, and proof that the deposit is still being held in my DT wallet.

Try clicking the "Check Bitcoins" button, and if still doesn't work,
send the tx to Di, the admin of DT.
I've been playing in DT since 2012 and it's been great ever since.
Maybe you did something wrong perhaps?
