hi, I am jacko48 just joined today,I bought a prs 500 sony reader approx 2 years ago for my wife as she loves reading,but its sat in the draw ever since as I thought I had dropped a clanger because I could not get books for it.I eventually found a few sites, Guttenberg,manybooks etc but all the books were public domain.Recently I discovered calibre ,now I can use it properly I thought ,but to no avail,every time I try to dowload calibre I dont get the welcome wizard therfore cannot tell it which device i have .If anyone could help me with this problem i would be very grateful.If anyone does know the answer could you give it to me as simply as possibe as i am by no means a computer expert
