Please Help,

I used to have in my wallet 10,500,000 DOLP, but now its all gone. I noticed that my transactions were not sent, so i decided to update. After the update i am left with 48k DOLP on my wallet. I mined for a few months back and I accumulated 10Mil. My address is D7dWmkBqihs9RefvV3TxauUpzUXJfSkj5m. Please help.
