Hello, I had an older version of the dash core wallet running, but it kept loading the block index forever (intro screen). It has been running for over a week without change. I stopped it and started again but no change. Now I downloaded the latest version today but it "thinks" it is the first time I have a dash wallet running on my PC. I am very concerned that I lost my previous wallet info and all my DASH. I made a back-up of my previous wallet some 5 month ago to a flash drive (dash.dat). Can I somehow restore my old wallet into my new wallet? I see the option "back-up wallet", which i did some time ago, but i cannot find the option "restore my back-up". Any help is much appreciated, as I am really confused now. Can it really be that I lost all my money?
