I've deleted my wallet when I whipped my computer recently and never backup my files. The only thing I've done was convert money into bitcoins and it was sitting in my wallet never touched. I reached out to the company that processed my conversion and they provided me with the necessary addresses that were used. How can I recover my bitcoins. Any help would very appreciated. Thank you.
