There is nothing wrong with that disk in the zip file. That means there is 
something wrong with your system if the demo will not work.

1) DIR will almost always show garbage with an OS-9 disk, which the demo is.
2) The demo uses OS-9 Level 2, which means you should be using a Coco3.
3) Are you running the demo on a real Coco or an emulator? If MESS, change the 
disk name from xmas86.dsk to xmas86.os9.
4) The OS-9 disk is formatted as a 40-track double sided disk. That won't be a 
problem with an emulator but will be difficult to convert to a real floppy if 
you don't use the right tools.
