While I'm pretty sure I didn't do anything wrong, and I'm absolutely 
certain that it worked perfectly yesterday, ConTeXt is broken:

C:\ConTeXt>path

C:\ConTeXt>context --version

And then I deleted it all, reinstalled Minimals, and get exactly the 
same result.  Is my luck really this bad?  What to do?
