Hello, I am totally new here. I was on Newzbin and was attempting to download an nzb file. I was using Winrar to unzip it and Grabit to download the file. When the file showed up in Winrar i double clicked on the file to start the download but then got the message "Windows cannot open this file". The version of Winrar is 3.8 and my OS is Vista 64 bit. Can someone please help. Thanks in advance.
