Yeah but.....these are zip files, and have to be unzipped, don't they? When I unzip them (I always do it into a temporary folder first before installation), I just end up with the two files, mission and properties. Don't see a "folder". What am I doing/interpreting wrong?

I mentioned my ignorance, but please keep in mind also that I'm 67 yrs old, and much of this stuff is starting to get really hard, for me anyway.

Thanks for your patience and help.
