I downloaded 001 to 008 files to be joined by hjsplit and everything was fine. I goofed up by going to properties of the 002 file. I changed 'windows shell common dll'(that was the default file type) to opens with 'internet explorer'. since then nuthings working. Even if i redownload it, its coming as a file to be opened by windows explorer... Now i cant browse from list that windows shell common dll. Can someone guide me how i can change it back to opens with 'windows shell common dll'???
