KFD_051.ZIP is KiteFlight demo (KFD) package, upgraded from 0.45
to 0.51. Some documents are still 0.45 level.
 
Compulsory figures are now in separate package (COMPUL10.ZIP), 
they are version 1.0 (!) and need at least 0.51 to run. This way 
new KFDs can be downloaded with less bandwidth in future. 
At this stage, make sure you get both of packages.
