I had the originial copy of IcewindDale II that I had loaded on an old desktop and and Sony Viaos laptop. Well after the last time I brought in the Sony I had to reload everything and somehow the Sony had deleted and important file from the disc during the previous load. I don't know how it did that but I could not load the game to any computer after that. Recently I found an Anthology which included Icewinddale II. This new disc loads the game directly to the computer. I was so happy to get the game back. I don't know how it's possible to delete a file from a non-rewriteable disc but the Sony did.
