I just recently purchased a Sony Vaio Laptop with windows 7 already installed. I have been having trouble downloading anything. When I attempt to download something I get the following error: part could not be saved, because the source file could not be read. Try again later, or contact the server administrator. I took it back to the store of purchase and they told me it was probably a newtork issue. However none of the other computers have this problem and my old computer with Windows XP did not have this problem. Any advice would be greatly appreciated.
