Hello all of you! Thanks for help me Piseth. Now I can download this books.Before I can’t download maybe because my flash I just scan&clean virus may flash yesterday. It has a lots maybe 20 viruses.When I download I see the word “completed” but I can’t open it I just see this file have been damaged and I can’t open it. I think that you a clever man because you are so young but your knowledge is higher than me. I am 20 years old. Now I study at CSIT for first year (programmer) but I am very poor at computer, but you are a smarter one.
