ok so what do you suggest please? im not super i.t savvy but kinda know basics. any help or advice would be great, i have bitcoins in there and thought they were safe saved away.
Firstly, back up your wallet. Open the windows file explorer and type into the top bar
%appdata%/Bitcoin
and hit enter. You should see a file named wallet.dat. Copy that file to a safe location.
Next, you should install the latest version of Bitcoin Core, 0.12.1. You can download that here:
