Scripts issue

I’m having problems with my scripts. None of them will appear in the menu. It’s simply a blank box. I’ve tried uninstalling and reinstalling Blender, and that didn’t work. I use 2.47, and I’d rather not switch to the newer version unless I have to. It’s a school course, and they only show how to work this version. I can’t continue without the Trajectory script. Does anyone know why I have no scripts, and how to fix it? Thanks!

Windows 7. I have Python installed, and the link didn’t help.
