Hi, it is my pc I am having problems with. I tried the command thing as per norbies instructions. I can't do that either, when I try it, it says:-

16 bit MS-DOS Subsystem

C:/WINDOWS/system32/command.com
C:/WINDOWS/SYSTEM32/AUTOEXEC.NT The system file is not suitable for running MS-DOS and Microsoft Windows applications.
Choose 'Close' to terminate the application

There is a bit at the bottom of the page that says if that doesn't work, try something else but I don't realy understand where I need to type it.
